Think: steady winds in excess of 30 mph, lots of snow or sideways blowing rain, above treeline or otherwise exposed. Do you reeeeeally need a Bomber Tent? Whether your answer is yes or no, what’s your response to proposing a camping kit – be it tent, tarp, or other – for ultra-foul conditions? Companion forum thread to the Bomber Tents Review.Aug 4, 2005 at 1:07 am #1339904
No experience in this area. Let me put my ignorance of these matters on display with the following question.
Can an ID eVENT Unishelter (31oz) be used in these conditions? Why, or Why not? I like this shelter for winter in New England. Haven’t used it yet on any exposed eastern mtn. tops (merely “hills”/foothills to you out west – though winds/weather on Mt. Washington in New Hampshire is supposed to rival the tallest peaks of the Himalayas).
I’m thinking low profile to wind. The bivy can be staked down with several stakes so it doesn’t blow away in the high wind. Great WPB eVENT fabric to help minimize the condensation possible due to the conditions (precip+no wind) & the small internal air volume, and to keep the moisture outside, …outside. Rigid, bent, sectioned-hooped Pole (not merely a bendable wire) in head area to keep snow from pressing the bivy against one’s face. However, must keep the one stake req’d for longitudinal pole support staked well in the high winds.
However, do I really want 2′ to 4′ of overnight snowfall [can y’all out West in the Rockies get 6′ overnight???] on top of me by morning? Will the fabric in the body section be flapping too much, unless it’s volume is filled with a cold weather bag?
Now, I know that I’m not the sharpest tool in the shed, so, what other points, pro or con, am I missing here?
If the eVENT ‘Uni’ is not appropriate for use in these conditions, what about the ID Sola (ok…difficult to get into) and/or MegaSola (a bit on the heavy side for what you get)? [too bad both of these can’t be considered bivies, & then made of eVENT to save a bit of wt – prob a 6oz to 12oz “guesstimate”, based upon a loose cp. b/t the Unishelter & the eVENT Unishelter.]
I’d be interested in knowing more. Anyone care to enlighten me on any/all of these questions/issues, please?

I note all the tents reviewed are domes. Now domes are NOT as stable as tunnels under really bad weather, nor are they as weatherproof. Why are there no tunnels included? Does no-one in America make decent tunnels these days?Aug 4, 2005 at 8:57 am #1339920

My short answer is no. I don’t need bomber tent provided the ground isn’t solid rock (e.g. I can drive stakes into the ground). I have been using a GG Spinshelter for around seven months. I have had a number of trips which I was exposed to 30+ mph winds, sideblown wind. I was find. Of course there was some condensation that dripped on me, but it was very minor.Aug 4, 2005 at 12:04 pm #1339932

Have used a Golite Hex this past winter during some downright severe weather in NH Presidentials, Stood up fine to 35-50mph gusts and heavy snow fall, had a few stakes come undone during the night but was impressed by the overall perfomance of this lightweight tent.Aug 4, 2005 at 6:30 pm #1339939
What about Stephensons Warmlite. The original superlite gear. Had one of their tents for years. Bombproof, lighter than any of these reviewed, actually made in the USA. Easy to pitch. Cutting edge in the 1960s and I’d say it still is cutting edge.Aug 4, 2005 at 7:06 pm #1339941
I’m with Jim… we also use a Hex 3 in conjunction with BMW bivys for alpine/bad weather trips … the space is luxurious for cooking in. The headroom is truly magnificent – changing clothes is too easy and you don’t have the damp gear in the attic in your face.. The condensation that forms when it is pegged to the ground in bad weather is not really an issue because the thing is so big you do not get to touch the lower sides anyway. With the conical shape, it is amazing how much the wind is shed from any direction, though you do get a bit of blown rain spray through the vents at the top. Because the Hex is so big and requires 11 pegs for a good pitch, finding campsites is sometimes a juggle. The Hex is also versatile. We have used it in heavy constant rain in a tropical rainforest to cold windy sleet at 3000m in the French Alps – this thing rocks!Aug 4, 2005 at 7:06 pm #1339942
can’t really speak for BPL, but three points worth considering.
1) if i understood the article correctly, there might be at least one more article (and reviews) in the “series” (not sure if this referred to the current “series” of four shelters, or if to a “series”of articles on this subject). Since this one dealt with some freestanding shelters, perhaps another article will cover some non-freestanding ones?
2) often a mfr must submit a sample to be reviewed – and then, not request that it is returned & hold the reviewers responsible for any possible damage to the product. not sure if/how this applies to BPL review policies in this case.
3) the article mentioned “new” shelters. some popular shelters wouldn’t qualify, solely on this basis.Aug 4, 2005 at 7:09 pm #1339943
Paul re the ID Unishelter, from experience, 8inches of snow on an unsupported bivy end is very cold! (how about a 3 pole bivy like the Bibler Tripod?) and I certainly wouldn’t want to spend a night and day in one when the weather turns really bad… like the folks in Patagonia had to…Aug 4, 2005 at 7:39 pm #1339944
Roger, as a fellow Aussie I have read your first rate articles. I also own a tunnel tent – the excellent Wilderness Equipment First Arrow – but I would certainly like to see any data you have that supports the idea that the large amounts of unsupported fabric on a tunnel tent makes them more stable/weather proof as opposed to good 4 pole design like the Bibler Fitzroy. Or are you comparing them to the cheaper types that really are more about being free standing rather than weather resistant? One of the advantages of tents like the WE or Macpac range is the quality of the fabric and design – they punch above their weight. But all things being equal, a good interlocking pole design with less unsupported fabric at the same tension must surely be stronger.
I know I only got my engineering degree from Melbourne (and it is not civil or mechanical!) and you Sydney chaps are sometimes more informed ;) but if you have any data on this would you mind sharing!Aug 4, 2005 at 11:12 pm #1339949

Hello everyone- I’m Doug Johnson and I put this release together. I’d be happy to explain a few things that you’ve found here:
1) You aren’t seeing bivy shelters because we tried to focus on 2-person tents that could handle the worst conditions- high winds, sustained heavy snow loads, and the possible need to cook and live inside for extended. However, there are certainly bivies and solo shelters that could survive serious winter conditions.
2) I hear you on the missing Stephenson’s tents Larry- I’ve been trying to get one of those to review for years! Not all companies participate. Then again, tunnel tents just won’t stand up to heavy snow loads like a tent with interlocked poles. I love my Hilleberg tunnel tent but its flat roofline means that it won’t shed snow like a 2, 3, or 4 pole interlocked design.
3) Like Paul said, you will also notice many missing ultralight bomber tents from this release such as the single wall Integral Designs and Bibler tents. For this release, we chose to focus on a smaller amount of great new designs. Of course, that doesn’t discount other excellent designs on the market.
4) Re: the Hex. Yes- great tent. I’ve spent several nights in a similar BD Mega Light and it’s been great. Then again, there are few who would pitch one of these on top of Rainier or high in the Himalayas. That’s more of the focus of this release- tents that can survive the absolute worst. For a review of the Hex and other floorless shelters that are great for most winter conditions, check this out:
The MSR Twin Peaks fits this too and its review can be found here:
Thanks everyone- good questions!
Shelter Systems EditorAug 5, 2005 at 2:28 am #1339955
Thanks for responding. Good info. Appreciate it.
Bibler Tripod – don’t know why I didn’t consider it.
Ingress/egress much easier than Sola & somewhat lighter too. Much lighter than MegaSola – though smaller.
thanks again.Aug 8, 2005 at 9:43 pm #1340086

The WE 1st and 2nd Arrow tents are not bad, as long as you get the wind drection right. The classic tunnel for extreme conditions is imho the (old) Macpac Olympus. I know the Olympus has been tested to over 100 kph many years ago. It has also been used around the world under all sorts of extreme conditions.
Why is a tunnel more stable than a dome? Because the poles in a tunnel are much shorter than in a dome. The shorter the pole, the stronger it is.
Also, many domes (no, not all) have the poles separate from the fly. You just throw the fly over the top.This means the poles can move relative to the fly, go into an S-bend, and the tent can collapse. In a proper tunnel tent the poles are threaded INTO the fly. They canNOT twist. Sure, some may say that makes such a tunnel a bit harder to pitch than a pop-up dome. True – but I am far more concerned with spending a comfortable confident night than with a few minutes of ‘convenience’.
The reason dome makers stress the ‘crossed poles’ is because poles which are not anchored togather at the top really are bendy and can collapse.
I don’t agree that a tunnel has long sections of unsupported fabric: far from it. I do agree that some tunnels have an unfortunate flat top: that’s because they are trying to use a straight pole rather than put a bend at the top. The bend makes the roof shed rain and snow far better.
I’ve made many versions of both designs, and used them under gale-force conditions. I trust my tunnels.

Some veterans on the nice (but not ultralite) UK site http://www.outdoorsmagic.com claim that tunnels flex better than geodesic domes, giving way temporarily to the worst gusts and then flexing back up again when the wind settles down a bit. I am unfortunately not an engineer either, so wouldn’t know how much merit that holds.
A really nice (but UK, admittedly) tent brand is Lightwave (http://www.lightwave.uk.com/) -eg. they have a 2-pole double-skin 1-person tunnel at 1.3kg. It does unfortunately have a flat top.
Their customer service has a very good reputation, it might be possible to persuade them to let this site test their tents.Aug 9, 2005 at 6:57 pm #1340122

Paul, Ryan recently made a post on another bpl thread praising the ID Unishelter bivy. Check out
Though I’ve never tried it, it seems like with a few tricks, a hooped bivy might be a workable way to go ultralight in extreme conditions. Like Dan suggested, I guess you’d have to deal with snow accumulation somehow.
But, what I’m really wondering is, how do you melt snow or cook during a storm if your sole shelter is a bivy sack? Any of you mountaineering bivy users have any tips to share?Aug 9, 2005 at 8:15 pm #1340125
Many thanks for taking the time to reply. I haven’t spent extended days out during the winter. I was just curious if my current overnight winter shelter would work for longer winter treks – even below treeline.
Snow is melted outside the bivy for drinking. Cooking is often not necessary as I often just eat GORP for several days + a multi-vitamin & mineral supplement.Aug 13, 2005 at 3:24 pm #1340279
Having backpacked over 200 Munros in one of the worst summers on record (1986) as well as gaining experience in Iceland and New Zealand, I feel that this is a bit of a specialist subject. So the first thing to ask is what do you consider ultra-foul? I mean, if the wind is above 10 metres/second the midges won’t be biting and rain always sounds worse on the flysheet than it really is. Modern waterproofs almost negate rain.
Today’s 12 miler round Snaefell took place in windy but humid conditions. Humidity means sweat and a major challenge for clothing. Humidity also stops the ground from drying out, a major challenge for groundsheets. And if the wind drops on a humid day, the backpacker is in big trouble from biting insects. However, my nightmare walking condition is extreme heat. Ultralight is the only possible solution.Aug 31, 2005 at 7:19 am #1341145
Tarps can be very comfortable in foul weather. Mine has beaks. I use one to block off the windward end and pitch the other end of the tarp high, with the beak horizontal, so that I can sit and drink tea as the rain is hurled past. The only real ultralight compromise is using a bigger tarp than the one Carol used in her Uintas trip.
In medium wind strengths my tarp flaps quite badly, far worse than a hooped tent, but there is the certain knowledge that an increase in wind strength would only pull pegs. The tarp and trekking poles are not going to break. Backpackers in latest generation tents don’t have that comfort. Hoops definitely do break (although I admit that the BBC said wind speeds had reached 90 mph when my Tadpole’s front hoop broke).Sep 6, 2005 at 12:09 pm #1341281
Hmmm, I seem to be the only person enjoying this thread, but walking through the storm has some sort of appeal – don’t want to speculate what – so here goes for another post.
We know what ultralight is because Ryan has given us a definition, but what is ultra-foul?
In the 1986 walk mentioned elsewhere I was wet to the skin on 23 consecutive days, including the day of my final Munro in round one. But, I was used to it and never felt uncomfortable till the water reached my groin. That is most definitely not my attitude today, so one of the aspects of ultra-foul lies in recent experience.
Another aspect of ultra-foul concerns the kit selected. I cannot help feeling that some of Ryan’s gear choices for his Lost Coast trip meant that he experienced more discomfort than he would have with slightly heavier kit. Nokian Trimmis, waterproof trousers and a Cave 1 would not have made the load unbearable and would have kept him both warmer and drier. (Ryan seemed to feel fairly happy with his kit in his summary.)
So if attitude and gear selection influence our definition of ultra-foul, perhaps ultra-foul just means we’ve gone too far with the kit we’ve got. That can happen with any approach to backpacking, not just ultralight.
Do we experience more ultra-foul days with ultralight kit? Perhaps, but ultralight kit also makes it easier to clear out to a more sheltered area.Apr 26, 2006 at 3:47 pm #1355510
Hilleberg makes a number of non-tunnel tents.
Unna specs: $400
4 lbs (64 oz) with 27 sq. ft. area,
40 inches tall, 2 interlocking poles. Sized on the threshold for 1-2 persons.Aug 24, 2006 at 12:14 pm #1361621
Sorry, Tom. Haven’t tried one, but one of the great virtues of the Akto, and the tunnel tents, is the vertical door on the inner. This feature really pays off in periods of prolonged damp. If the inner door is vertical, condensation is unlikely to fall through it on to your sleeping bag. And something I really like is being able to sit with the flysheet door open while rain falls. Tea in hand, warm sleeping bag and – I know it isn’t very ultralite but – good book to read and I feel very snug watching the wet, grey world outside. I don’t think you could open the flysheet door on the Unna or the Jannu during rain without getting the inner wet. However, I’m only looking at the pictures in the 2005 catalogue.Nov 2, 2006 at 10:13 am #1366048

A few years ago I camped in Koke’e State Park, above Waimea Canyon on Kauai, and on New Years Eve the rain ultimately angled at about 80° to the ground with sustained winds of 30+mph. The wind direction shifted a good 90° halfway through the night. We were on sloped ground well away from the lowest point, but when we awoke even the slopes retained 2″ of standing water.
In such conditions, a bathtub bottom tent made all the difference. With the wind shift, a freestander can just be unstaked, rotated, and re-staked. We were sleeping in a river – there was nowhere that wasn’t! Groundsheets would have been overrun by the runoff.
So, all told, for me there’s sometimes a benefit of even an UL tent in UF conditions, to speak nothing of the mental benefit/comfort, which is entirely more subjective. Now that rain’s returned to us here in Northern California, this sure is a timely topic…
Fun to see everyone’s varied opinions on this interesting topic!Nov 2, 2006 at 2:45 pm #1366074
