Let's assemble an awesomely ultralight 4 season, extreme weather shelter system!

The idea of having a single tent which can be customised to minimum weight for all 4 seasons is a pipe dream. It just doesn’t work. As your life can depend on this tent functioning, the sort of compromises you are thinking of are … unwise maybe?

Having a complete vapour barrier on the INNER tent is a seriously bad idea. You will get heaps of frost overnight on the inside of the inner, which in the morning will get you and your gear wet, plus you risk running low on oxygen.

Air beams … chuckle. A poor idea which went nowhere.

The idea that it might be that easy to upgrade a Hilleberg tent just like that is (something) but cannot be taken seriously. Hilleberg have a very long experience in this game: they know what they are doing.

Z packs no longer does custom work.

I have my winter shelter and a couple of three season choices. This has worked well for me.

Michael,

As Roger said, replacing the inner of a Jannu (or any double walled tent for that matter) with cuben would be extremely unwise.

The most important reason why double walled tent inners are made from lightly water resistant, but very permeable fabric is to push the dew point out beyond the inside of the first layer, where vapor will condense on the inside face of the outer layer.

While many of us have searched high and low for that one tent for all occasions, its always important (especially in potentially dangerous weather) to make sure one has the “right tool for the job”.  Therefore, I’d suspect many of us have more than one tent, depending on the trip.

Infact, I’d suspect many of us probably have too many tools to choose from!  :)

“Too many” is in the eyes of the beholder. :)

Cheers

btw helleberg uses 1200d kerlon on the jannu (STRONG STUFF!)

Kerlon 1200 is 30d ripstop nylon.Silicone coated on both sides.

frost overnight on the inside of the inner, which in the morning will get you and your gear wet, plus you risk running low on oxygen.

I kind of realized this earlier, so I began looking at very light dehumidifiers, which sent me down another interesting rabbithole…check out roshal micro dehumidifiers/humidifiers …very interesting stuff…

The inner would have had vents, however, the cuben inner in theory would have been made near identical to the default one, though I guess, that might still not be enough due to the material difference…

might just abandon the concept all together and get the zpacks dublex 2 for 3 season and a sub 2 pound northface bivvie for cold….would need to have something for snow loading though dont want to get buried alive

7 lbs isn’t heavy given the context and really is a compromise between weight and strength. I’m looking for an Arctic winter tent myself so watching where this thread goes.

Cant a person have two tents?

And to get REAL extreme… two sleeping bags?!?!

What do you mean only two?

Winter and deep winter?

I suppose youre right. Theres alpine winter, also.

Infact, I’d suspect many of us probably have too many tools to choose from!  :)

Sigh! 5 tents, 3 bags, 3 backpacks.  I’m not even going to pretend that those numbers won’t increase, nor do I doubt that there are plenty of folks out there that make my paltry stash look silly.

The thing is, I use every single one of them when the time is right.  There is no single piece of gear for all conditions.

What about the the Stephenson’s Warmlite 2R tunnel tent?

Still would like to know what winter experience our OP has and where does he plan on using this system.

You know, so we can find out why what is already available doesn’t work.

We reviewed the 2R in our survey of tunnel tents. I was definitely NOT impressed. Design, space and quality all poor (imho).

Cheers

Very little. I have slept outside in an igloo twice, in NC. So virtually none. However do not be alarmed. I have disposable income, and do not plan to actually venture into anything too treacherous anytime remotely soon. I am only looking for a tent like this because as I grow, I will not have to buy a new tent for some years potentially. and in the case of some kind of freak weather during my learning sessions I have something very safe. Potentially as I advance my skillset, I can be using the same tent. Saving money by planning ahead. and planning for the worst, while my skills are low, might save my ass

I second Roger’s opinion on the Warmlite tents. I would never buy one of their products again.

For a truly stable shelter I would look at tunnels but if you’re not into those I’d have a look at the Crux tents from the UK. I had to deal with them for an issue on an old climbing pack and they were very helpful. A stand up company!

Roger,

Did you ever review a TNF Westwind?

The original version?

For the OP, the Westwind was a four season, 5.5lb tent by The North Face. While they haven’t made it for many years, I’d suspect they might be more available in the US than a MacPac Olympus.

Link?

No, I have not managed to get hold of a Westwind. I gather they went out of production many (many) years ago. That figures: companies always discontinue their best products in the hope you will buy what marketing thinks is an upgrade. It never is.

But yes, it looks as though TNF may have copied it from Macpac.

Cheers

“But yes, it looks as though TNF may have copied it from Macpac”

If TNF did copy it, they didn’t to a good job, imho.

When did MacPac come out with the Olympus?

I remember selling Westwinds while working in a gear shop in ’87-’90. I think the Westwind came out in ’80. (Too bad there weren’t no internet back then. Hilleberg, Noall, MEC, Macpac… they were whispers in the wind to me.)

> When did MacPac come out with the Olympus?

Hum – lost in the shades of time. Must be some time in the 70s I guess. Macpac started in 1973 with packs, but the Olympus was one of their first tents.

Cheers

I just looked at the Lightwave site and figured you could be interested in their Arctic and Mountain series… just food for thoughts…

They are not bad tents – both the tunnels and the geos.

However, their persistance with side-entry makes their tents extremely long. This can be problematic in finding a tent site – or need a whole of extra work stomping the extra length of snow down.

The sleeping end of their designs is very low – OK for your feet but you could not have someone sitting back there out of the way. That becomes very awkward when one of you is trying to cook dinner at the vestibule end.

Pity.

Cheers
