Bombproof Geodesic 2 Man Mountain Tents

height="365">

Have you considered the Hilleberg dome tents?

Worth a look http://www.crux.uk.com/en/crux_tents.php

Horribly heavy. Why not a tunnel tent such as the Macpac Olympus?

Cheers

The Olympus is a tunnel, not a geodesic.

I heard bad things about the poles of the Crux…

And Hillebergs in the UK are ludcriously expensive. Literally going to cost £200-300 more than these!

I have one of the older Crux models and the poles were a issue, they upgraded them later. I replaced mine with eastons. The replacement poles were priced fairly reasonable. When I replaced mine the tent pole company felt that the lack of pre-bend was a major problem. The Crux gives you a gives you a bombproof tent for a little over 6 lbs. There was a review of it a few years back on this site.

Where do you plan on using it?

Mainly in Scottish Winter but in a year or two, the greater ranges

Dont know if this helps but, there is a tnf mountain 25 on Geartrade for $313.20. says it has never been used.

On a high expedition, we had an assortment of tents, but the Mountain 25 and its brothers were well-represented. We had to have bombproof shelter, and the 2-man and 3-man versions did very well. Mine is the 3-man version, and we have squeezed four into it. For sure, it is my choice for high winds.

Hi Paul

> The Olympus is a tunnel, not a geodesic.
Very true.
I can understand the desire for a bombproof tent of course.

What I don't understand is why it has to be a heavy geodesic when you can get the same stability from a lighter tunnel tent.

Cheers

what about the Black diamond tents like the bombshelter, Stormtrack or tempest. Also Marmot Thor tents are basically the same as the mountain 25 and trango.

Considering your requirements, I can endorse the Mtn 25 based on personal experience and feedback from several friends and customers. I own one of these, and rely on it for winter use where I'm able to pull a sled, or on canoeing trips where weight is not a primary factor in gear selection and a little luxury improves the experience.

You will not likely find a stronger tent in its size and price range. Ordinarily I'd point out that the fly is traditional nylon and could be lighter if replaced with silnylon, but the abrasion resistance offered by the heavier fabric is essential for extended periods of high winds and blowing snow. Excellent space inside too, but that's also mandatory if you're stormbound and have lots of insulating gear and clothing.

Again, this is one HEAVY tent, but it will hold up very well both in extreme conditions and over its lifespan. In a past job I handled warranty processing for an independent outdoor retailer, and had a customer with a 15-20 year old version of the Mtn 25 which they had me send to TNF for a replacement zipper. It was a well-worn and tired looking piece of gear, but it was still storm worthy and their 'go-to' tent for camping on the BC coast (super wet).

Roger – how can I be sure of that? I don't see any tunnels on high mountain expeds? But I really respect you so would love to hear how.

Paul

you could probably find an exped Polaris tents in Europe for a good winter shelter.

Paul, Check out the Vaude Power Odyssee

I have been considering it, but have not used one yet. The specs look great, but they may be off by more than a bit. The power frame evidently performs really well in gales and the price is fairly decent.

Hi Paul

> I don't see any tunnels on high mountain expeds?
Oh yes, I know, so let's look at why and what this means for you.

Expeditions in the Himalayas etc usually have lots of people and lots of porters. You have only to look at a typical scene at Everest Base Camp. This has several consequences:
* Weight does not matter: porters are cheap
* Expeditioners like big tents so they can all sit together playing cards (or whatever)
* The expedition doesn't want to spend a fortune on expensive tents
Big heavy geodesics satisfy these criteria. But many of the tents you see on expeditions are 3 and 4 man geods. They don't have to be all that sleek: move up to 70+ d nylon and 10 mm poles and they will take an awful lot of abuse. Hey – there's even a bakery at EBC!

The TNF 2-man Mountain 25 is ~$500 but weighs nearly 4 kg
The 2-man Qasar is 450 UK pounds but weighs over 4.3 kg
The 2-man Trango 2 is ~US$525 but weighs over 4.1 kg

The 2-man Macpac Olympus is 3.1 kg but it's NZ$900 bought in New Zealand: a bit more when bought overseas. That's a lot more dollars.

The double-skin geods usually require you to pitch the inner tent first and then to throw the fly over it. That's OK in fine weather, and who cares at 7,000 m in a snow storm anyhow? But try pitching one in seriously wet weather: the inner tent will fill up with water while you are securing it. Pity about that! And since the guy ropes are attached to the fly while the rather long poles are attached to the inner, embarrassing things can (and do) happen in a gale.

The single skin geods pitch more easily, but very few have good ventilation so they do collect condensation. And rarely do they even have a vestibule. Hard to get in and out in the rain.

Have a wander around YouTube. There are quite a few amusing videos of people trying to pitch a geod in a strong wind. They have a lot of trouble trying to hold the inner tent up without snapping poles while someone else tries to secure the (wildly flapping) fly over the top.

A tunnel tent has short hoop poles, and shorter poles are stronger. A good tunnel tent is pitched fly-first; the better ones have 'integral pitching' – both inner and outer at once. Rain does not get in because the fly is always there. A good tunnel tent has the poles attached to the fly, which makes it significantly more storm-proof. It is quite easy for one man to pitch a tunnel in a howling storm without risk. (How do I know? … ) And they have good vestibules.

So why are there so many geods and domes on the market in America? Dunno – I suspect cheap free-standing pop-ups started the fashion and the geods were a natural progression. But go to somewhere like Northern Europe where they know about bad weather, and you find the Hillebergs and similar with their tunnels.

Of course, our neighbours the Kiwis (New Zealanders) will simply smile at all this, because they have their own little weather system down there. The Maori name for NZ is 'the land of the long white cloud'; visitors sometimes translate that as 'the land of the long black never-disappearing cloud'. Some places in Australia have similar weather: the Main Range during winter for instance. 100 kph winds (with white stuff) are quite common in both countries, but the weather can get worse…

A final thought. What happens to a geod when it loses all its guy ropes? Embarrassing – a lot of flex. What happens to a tunnel when it loses all its guy ropes? Not much if the wind is any where near end-on. Yes, field tested … :-)

Sooo… what an expedition buys for the porters to carry, and what an individual should buy to carry himself, can be a bit different. What should YOU buy? That's up to you of course (and your budget!).

I was just challenging the apparent assumption that only geods can be bomb-proof.

Cheers

Thank you Roger. Very thought provoking. Some comments:

1. What are the excellent tunnel designs on the market besides Hilleberg? They are just so expensive here in the UK. Particularly interested in those that pitch together.

2. What weight do you think I should be aiming for, then?

3. I require a comfortably big vestibule. For example I will probably camp ay, say the base of a Scottish Mountain for a week for various mixed climbing escapades without moving my base. Can a big vesitbule really happen plausably in a tunnel with strong winds?

I've been camping in the Scottish Highlands, summer and winter, for over 30 years, and have never bought a full geo tent. I've used everything from the old cotton outer Force 10 A pole, to my present Stephensons 2R in winter.
As Roger has said, trying to pitch a 'stand alone' tent can be almost impossible in very high winds. A tunnel tent is much easier to pitch, especially when solo. Ease of pitching in wind is much more important to me than a tents ability to handle a big snow load.
I wouldn't worry too much about snow losding in Scotland. The huge dumps that fall in a couple of hours elsewhere, are pretty unusual in Scotland. A quick shake of a tunnel tent will get rid of most snow.
Tunnel tents are noisier, and move about more in high winds. If you are of a nervous disposition, ear plugs and a nice single malt takes care of that. :)

I'm going to disagree with Roger and Mike here. I've pitched geodesic domes in very high winds and pouring rain many times and never had a problem. Pegging down one end of the tent stops it blowing it away and with any decent design the inner isn't unprotected long enough for it to get very wet let alone fill with water.

That said, tunnels are lighter weight and can be as wind resistant if pitched end on to the wind. As Mike says they are noiser and do flap more. And if the wind changes direction and comes from the sides they can shake.

Geodesics aren't only used on expeditions because of the size. It's also because they can withstand heavy snowfall and are easier to pitch than tunnels on snow ledges and in rocky terrain. I remember a talk by Alan Hinkes in which he showed geodesics on a snow ledge high in the Himalayas that had been left for a few days while the climbers went higher during which they were buried under several feet of new snow. Once dug out the tents were still standing. Tunnels would have collapsed.

All that said I would only choose a geodesic for extreme conditions. Tunnels are lighter and will cope with almost everything. And I'd go for Hilleberg tunnels both for design and durability – I used them when I lead ski tours in places like Greenland and Spitsbergen and they withstood some horrendous weather.

I was basing my opinion on watching others trying to pitch full geos in high winds, Chris. I wouldn't want to do it on my own. Like i said, i've never felt the need to own one myself. I had a semi-geo a few years ago, and found it much more difficult to pitch than a tunnel in high winds.
