<< Part 2: Downsize your pack

3. Ditch your dome.

According to


, the dome tent is "the low-hanging fruit of an ultralight makeover." I have no idea what that means, unless it implies that reducing the weight of your shelter is an easily reachable goal. The magazine correctly points out that you can cut your shelter weight by a half or more by switching to a lighter alternative, and suggests a tarp as the lightest option with the highest space-to-weight ratio. You can't argue with that.

Their recommendations include the 

Integral Designs SilWing tarp

($110, 12oz, 56 sq.ft.), or the

GoLite Shangri-La 2 floorless shelter

($225, 1lb 10oz, 45 sq.ft). For the tent aficionado, they propose a

NEMO Meta 2p

($225, 2lbs. 15 oz., 36 sq.ft.), or a

Mountain Hardware Lightpath 2 hoop tent

($175, 3lbs 15oz, 30 sq. ft.).

Setting aside the Lightpath 2 for the moment, which surely must only be present for some kind of sponsorship obligation, their suggestions are not that bad. The SilWing is a pretty good tarp, if a little trickier to erect than other designs. The Shangri-La 2 is also respected, as we'll see later. I've never seen a NEMO Meta 2p, nor heard of anyone using one. To me it looks over-designed, and from what I can tell, it would be easy to achieve the same result for less weight with a tarp and an inner.

In any case, some interesting suggestions – but are they the best? Let's look deeper into dome-ditching to find out...

Backpacking North


The good old dome tent! Roomy. Stable. Easy to erect and move around. Or is it? Is it really any more roomy than some of the other options available to us? Yes, it's stable – especially if it's got a nice geodesic structure – but complex structures come with a price: poles. Lots of them. Big, dangly, fold-away poles, held together with elastic cord, featuring

bizarrely complicated joints



to create as

sci-fi a shape

as possible (I know not all of those examples are strictly dome tents, but as a generalisation, you get my point). Then, of course, there are lots and lots of tie downs and guy cords to make sure your easily moveable shelter doesn't, well,

easily move


Mainstream manufacturers release a veritable plethora of tents every year, all designed to appeal to our senses and impress us with their technological ingenuity and perfection. I suppose the idea is that the more high-tech they are, the more we are likely to feel secure in them at night. Their latest tent will be the perfect shelter for all your needs, and hey, it's ulttralight at 5lbs! 

In reality, of course, there is no perfect shelter. There are only shelters appropriate for your needs, for the environment and climate you will be in, the time of year, the expected conditions, the amount of bugs etc. Traditional tents tend to be ridiculously over-engineered. You really do not need a double-walled tent with integrated bathtub floor and separate groundsheet/footprint to protect that floor. Traditional tents also weigh a ton. They are often not particularly well constructed, and with an abundance of seams it's inevitable that they will leak. And yet they remain so attractive... 

For an ultralight approach, we need to embrace a shift in values; we must accept that

all that extra stuff

 is not needed. A shelter can be simple. In fact, that is precisely what the name suggests: it is a


, not a second home. It must protect you, keep you dry, offer you a place to hang out in poor conditions, and, ideally, not take up 75% of your pack weight (and space).

So let's begin by simplifying the structure. Instead of two walls (one to keep out the rain or moisture, another to keep out the rain or moisture that the first one doesn't keep out), can we manage with one? 

One wall or two? 

We've been told we need two walls in a tent to keep out condensation, and provide an additional layer of protection from rain. But is condensation really all that bad? It only becomes a problem when you come into contact with it, or when so much is produced it splatters off when pounded by rain. In order to reduce condensation, tents are designed with ventilation flaps and other contrivances to encourage airflow. With that taken into consideration, what if, instead of fighting condensation, we simply accept it as part of the experience? Then we quite literally open up our shelter options.

Most ultralight shelters are single wall, floorless designs, either in the shape of tarps (essentially a sheet of material suspended as you choose to create an open shelter), or in the form of an enclosed (i.e. zippered) or semi-enclosed pyramid-style structure. There are many variations on these two designs, but in principle tarps and pyramids make a simplified categorisation.

But what about condensation?

To which I say: So what about condensation? Yes, it happens, somewhat inevitably. 

Because tarps and pyramids are designed to be open or raised shelters, there is plenty of airflow through them. But you will still get condensation from the temperature differential between your shelter material and the air. 

You don't even need to be in or under it to find moisture building up on the iside of your tarp (for much more info on condensation 

see the link to a Backpacking Light article at the end of this post)

Typically, the amount of condensation

 is nothing a micro-towel or a good shake can't deal with, then when you pack up camp you simply stuff the shelter into the outside mesh pocket of

your new ultralight backpack

, and hit the trail. You can always stop to dry it off if the sun is shining.

As for protecting your gear whilst you're inside the shelter, often there is so much room under your shelter that it simply isn't an issue. If you do brush up against it, it's not usually enough to wet out your nice fluffy down sleeping bag – which is what we really want to avoid. Some bags and quilts have a heavier duty material on the footbed and shoulder areas, or are constructed entirely out of a more water resistant material, and can be used under a tarp without the need for additional protection.

However, to be on the safe side, many ultralighters take along a bivy to use under the tarp or in their shelter. This adds a layer of protection against condensation, and the ingress of rain and/or bugs.  Bivy bags typically weigh very little – far less than an inner tent – and, assuming you have a fairly good idea of the weather conditions, offer the flexibility of sleeping inside them without erecting a shelter overhead. When you combine a bivy bag (or bug inner) with a tarp or pyramid you effectively have a very flexible, modular system: a kind of two-wall shelter, that you can adapt to different situations and conditions.

It is this flexibility or use which we seek in the ultralight world. Why be limited to the defined design of a tent when you can have multiple shelter options with you: tarp only, tarp and bivy for rain/bug seasons, bivy only, or tarp and bug inner if you live in particularly hellish mosquito country. You carry with you the best of all worlds, and can adapt to the situation with ease.

So to summarize: don't fear condensation. When you think about how it magically forms out of thin air, it's quite a beautiful thing. When you consider that some tarps weigh a mere 200g (7oz)

or less,

  even after adding the weight of stakes, cord, and seam sealer, you might still have shaved off up to 4 lbs (2 kg) from your load. Not bad.

How about no walls at all?

The logical extension of all this is to skip the shelter altogether if you know the weather is going to be fine. That's a nice idea, but I have yet to go hiking anywhere where the weather is 100% predictable. Even in desert climates I'd still take a simple tarp as shelter, and sleep under the stars only if conditions seemed appropriate. If it does rain, at least I have shelter. The weight of a tarp is a small price to pay for safety.

Sorry, did you say floorless?

In a tent, you usually have a floor. Then often another floor to protect that floor from the ground. With a tarp or pyramid shelter, there is far less between you and Mother Earth. There are advantages and disadvantages to this, the main advantage being, of course, less to carry. The main disadvantage is an increase in condensation, but this is largely compensated for by the open, ventilated designs of the shelters – and anyway, we just learned not to fear condensation anyway! Love it for what it is!

Personally, I think that it is precisely the proximity to nature offered by tarps and pyramid shelters that is their main attraction. To wake up under a tarp and see morning mist rising off dew-covered ground is something quite special. Throw in a couple of deer cavorting in a nearby dell, and you have an idyllic scene to accompany your morning oatmeal. Why hide away in a tent when the whole point of being outside is to be in nature. Under a tarp you are much closer to the environment, and your experience will be all the better for it.

Nevertheless, sometimes we need a little protection from the elements. It would be a shame to have to camp on less-than-ideal ground and get mud, sand, or moisture in our gear. The simplest solution is to carry a small sheet of




to provide a barrier between you and whatever surface you camp on. It need only be a little larger than your sleeping bag, and weighs next to nothing. Another option is to simply use a bivy; most have a more durable, waterproof material on the base.

A typical tarp setup: SpinnTwinn and LT4 poles, Katabatic Bristlecone bivy, polycryo sheet, z-lite section.

Naturally, as with any tent, you'll probably want some form of insulating barrier between you and the ground to keep you comfortable and warm in the night. This will most likely take the shape of an air or closed-cell foam pad – and we'll look at those and some alternatives in part 4.

Ah, but I live in bug country...

There are several ways to cope with bugs. Many summer bivy bags feature a bug window. Tie the bivy hood up to the top of the tarp, zip up the hood, and sleep in peace. Some bags feature a larger area which can be suspended or raised to give a less claustrophobic feeling. For the ultimate in luxury, and in my opinion indispensable in places such as Lapland and Minnesota, a solo-sized mesh bug inner will keep the bugs at bay and give you a little room to keep your sanity intact. There are as many bug inner designs as there are tarps and pyramids, so check out the manufacturer links at the end if you are blighted by bugs.

Aren't tarps hard to pitch?

Honestly, tarps and 'mids are no more difficult to pitch than any other tent. I'd even go so far as to say they are easier. A couple of stakes, some tensioning, maybe (but not necessarily) a knot, and you'll have a shelter more taut than any dome.

So which are better then, tarps or pyramids?

Neither. It all depends on where you'll be going and the conditions you expect. Tarps offer great flexibility: hang them high for palatial roominess, or hunker down to the ground in bad weather. They are more suited to forested areas or low country – they are not really intended to withstand very high winds. 

Pyramids on the other hand are great for variable climates and/or winter use, but can still be opened up to create a lean-to like shelter. They also offer plenty of headroom if, like me, you are on the tall side. They shed wind better and, as they are surprisingly sturdy, can be used more readily in open spaces.

Are there any other options?

If you really can't stomach the idea of a single wall shelter, there are a few well regarded ultralight tents out there. Using simpler, lighter materials, they offer the same comforts as traditional tents but usually with a higher price tag. Alternatively, how about a hammock? There are a couple of ultralight hammocks with integrated bug netting, and a tarp rain fly for around 700g. Pretty good, if that's how you hang...

All right then, you've convinced me. So what do you use?

My journey towards using ultralight shelters was probably fairly typical. A few years ago, I was in InterSport in Rovaniemi, and made an impulse purchase of a Haglöfs Genius 21 dome tent.

A big, heavy Haglöfs Genius 2 in a very nice setting.

It was spectacular. I loved it. Small, Norwegian pensioners admired it at the top of large Norwegian mountains. It weighed a ton! Remember the

343 principle I wrote about in part 1

? The Genius 21 weighs 4kg (8.8lb)! Not so genius after all. Sure it could fit 2.1 people (go figure), and when split between two it wasn't quite so bad to carry. But When I took it on a solo hike with my dog (who, incidentally, refused to carry half of it; so much for man's best friend) I was utterly exhausted. Great tent though. Tough. Reliable. Green. I

took it to Utah

last year with a friend. It was such a pain to pitch in the high winds blowing down from Forty Mile Ridge. So much for the ease and simplicity of a dome. (Well, to be fair, it would have been hard to pitch anything on slickrock with a storm raging.)

Just before moving to Minnesota, I decided I wouldn't carry such a ridiculous weight with me ever again, and went in search of a solo tent. After reading recommendations in

Colin Walker

's and

Chris Townsend

's books, I plumped for a

Hilleberg Akto


The Hilleberg Akto in stealth mode. Can you spot it? It's behind the tree.

Perfect for one man and his dog. And much lighter than the Genius at 1.4kg (3lbs 2oz). Today, that seems to me like a fairly heavy shelter, but if you compare it to


's Lightpath 2 recommendation, it's about 13 oz lighter (albeit for a solo tent). I still like the Akto. It has great nostalgia value for me. It's a great tent for Lapland, and good in winter. It's cozy and very well made. But sadly now I rarely use it.

When I finally decided to truly go ultralight, I took a dive off the deep end and purchased a Gossamer Gear SpinnTwinn.

The Gossamer Gear SpinnTwinn. Now that's what I call a taut pitch. And just look at that catenary curve!

A simple tarp, made out of spinnaker fabric, (used, like cuben fiber, for yacht sails). When it arrived through my post box, I couldn't stop grinning. It weighs 300g, seam sealed, with cords attached. Let me repeat that:


(something like 10oz) – and that's for the two person SpinnTwinn. That's 3700g lighter than the Genius 21. Or 1100g lighter than the Akto. It felt as if weighed nothing at all. I still laugh deliriously when I think about this. I'm doing it now.

And the fact is, it's a great shelter. Simple to pitch, easy to re-pitch and modify if the weather changes. Beautiful. Elegant. Its taut catenary curve is truly something to behold. To see the world slipping into darkness under it is so soothing. To wake up under it is an invigorating delight. I feel more a part of nature under the SpinnTwinn than I do in any other shelter. Admittedly, compared to a really basic rectangular tarp (without a catenary curve) it is a little limited in pitching options (or at least, you need some creativity and skill) but I love it. It achieves everything I need.

So why did I need to go and buy a DuoMid?

Well, under a SpinnTwinn in bug country you are going to want some protection. A bivy is fine, but a little limiting. Also, I wanted something for the more exposed conditions of Lapland, and something that I could use in winter – something, in other words, with a door. The SpinnTwinn is great but in a snowstorm... no thanks.

My Mountain Laurel Designs DuoMid has a bug netting perimeter to keep the worst of the mosquitoes at bay, and can be pitched high or low for additional space. It is already huge, with more than enough room to sit or half stand. Pitch it high and it becomes palatial. Open the doors wide and it's like my own personal laavu (lean-to). I can shut out the wind and the snow. I can cook inside. I can fit all my gear in and still have room to lounge around. It's light – 614g – still 3400g lighter than the Genius 21, and like the SpinTwin pitches perfectly with my trekking poles (just one, in fact). Plus it has one additional feature...

It's bright yellow.

Sunny, yellow, DuoMid, joy joy.

There's a lot to be said for blending into the landscape, but there's a lot more to be said for waking up under a sunny yellow pyramid of joy. These days, I reach for my DuoMid more than any other shelter when heading out. Although sleeping under a tarp is wonderful, there is something about the DuoMid that just feels


. It might not be the lightest pyramid or tarp, and I will definitely need a really good bug inner to truly cope with the summer mosquitoes in Lapland that will push the weight up a little more, but sometimes, you know... weight isn't everything. I'm still carrying less than ever before. I'm protected from the elements. And I'm happy. And that's what counts.

For a bivy I use a

Katabatic Gear Bristlecone

 (200g / 7oz) – a truly great bivy with plenty of room for all-year-round use, and a huge 180º bug netting window. As it has a waterproof floor, so I don't really need a ground sheet, but I generally take a 46g / 1.6oz sheet of 


, just in case.

As I mentioned earlier, the shelter you choose must suit your needs and the environment you most often hike in. No one shelter will be perfect for every situation. What's good for Lapland is overkill for Utah. When you're choosing a ultralight shelter, try and take a look at what ultralighters in your neck of the woods are using. It's highly likely that their gear choices will be appropriate for you. And with that thought in mind...

What do other people use?

While researching this article, I was amazed how many tarp configurations are available from different manufacturers. MLD, for example, offers seven versions of a simple rectangular tarp (and that's before we even get into TrailStars). As the emphasis of the

Ultralight Makeover

series is on proven gear, I'll once again be focusing on exactly that: gear which other bloggers and hikers regularly use and recommend.


If there's one thing to say about buying a tarp it's this: size up. They're so light you can afford the luxury of a two person shelter, and when you are stuck under one for a day you'll be glad you did. The weight penalty of choosing a two person tarp over a solo is usually negligible compared to the benefits of larger coverate.

Gossamer Gear SpinnTwinn

Probably the most popular tarp around, perhaps because it is so easy to set up. With just a couple of trekking poles (I use

Gossamer Gear's LT4

poles which are a match made in heaven) you'll have it up in under five minutes. The catenary curve limits its pitching options a little more than a straight cut tarp, but creates a very taut pitch that rain just trickles off. The taut pitch is important as spinnaker is a fairly noisy material, and a well stretched pitch will limit any unpleasant nocturnal flapping (from the tarp... other wind noises are your own problem). I recommend switching out the provided spectracore line for a slightly thicker (maybe 2mm) cord. I find spectracore stretches when wet, causing the line to slip in the corner and side linelocs. The SpinnTwinn weighs a mere 238g before seam sealing and without the cords attached, and costs $175.

Gossamer Gear also make a more enclosed, solo version (the


), and a super light cuben fiber version, the


, weighing just 156g, but costing $335. For the most bang for your buck, you can't beat the SpinnTwinn.

, at least until he got a...

Hyperlight Mountain Gear Echo I / Echo II

The HMG Echo is a nice modular tarp system. It takes the traditional rectangular tarp design and adds a few elements to make it more suitable for a range of conditions. The tarp itself is not dissimilar to the SpinnTwinn or CubicTwinn, but the accessories make it an interesting shelter.

The beak

 encloses the front, and

the inner

transforms it into an integrated double-wall, bug-free shelter. As with all cuben fiber gear, it's a bit pricey at $270 for the Echo I, and $295 for the Echo II. As there's only a 1oz difference between the two (the Echo II tarp comes in at 9oz / 255g incl. lines) once again it pays to get the larger size.

I like the look of it, and so do






even thinks the beak can be used as a mini tarp, but then he likes dressing up as a penguin.

Many of the ultralight tarps use exotic materials and designs, and consequently cost a lot of money. However, if you're on a budget, there are a lot of basic rectangular tarps which in some ways are more flexible as they offer an almost infinite variety of pitching options. While writing this article,


recommended a 

Alpkit Rig 7 tarp

, which weighs 497g / 17.5oz, seems like a pretty good deal at around  £45.


There is one shelter that has risen in popularity recently that, being semi-enclosed but doorless, doesn't fit into either of the main categories:

MLD TrailStar

Falling somewhere between an open tarp and a pyramid shelter, Mountain Laurel Design's TrailStar has proven very popular, especially it seems with people in the UK. It might well be that its combination of luxurious space, simplicity of pitching, and the open "alcove"style entrance is perfect for the inclement British weather. Many people claim that its wind-shedding abilities are unsurpassed, and it certainly looks very sturdy for its 16oz / 450g of silnylon. It's a good example of a shelter that suits a particular climate, I think, and I'd hesitate to make it my main shelter in Lapland where, as it were, I need closure.

The Pain Cave


Pyramid Shelters

Basically, a tarp with a door, constructed typically (but not always) around a single pole to create a super-sturdy single-wall shelter. Not all are pyramid shaped, but it serves as a good indicative categorization.

MLD DuoMid

By far the most popular pyramid shelter of them all, Mountain Laurel Designs knocked out another winner with the DuoMid. With their excellent construction and array of build-to-order options, the DuoMid is, perhaps, an ideal shelter. Pitch it open, pitch it low, get it with a bug netting perimeter, use it in winter (although it'll take longer to pitch) – it's such a good all-rounder. 16oz in silnylon, 12 oz in cuben fiber. But don't take my word for it. Witness the joys of yellow, grey and white at
