Bivouac sack, bivy, bivvy, bivi bags and bloody bivvying

I pull my buff from my neck up over my face and they don't bite through it.

I've got a friend who does this. He wears his cycling cap to sleep in, and the peak keeps the buff off his face a bit. Works as both bug shield and black out curtains.

Props to you for being able to sleep like that. I need to gulp vast amounts of fresh air in order to be able to snooze comfortably.

Cycling cap + hat neck thing sounds like a winner. I'm going to learn to sleep on my back asap.

Yeah, it was exactly what I needed.
I didn't feel sweaty in it but it did get a bit of condensation in it, but nothing to make it void of use.
I used it in a tent with only the outer to shelter from rain. On top of a matt with my feet on the wet grass it stood up very well. It was comfy and pretty roomy considering it packs up to the size of a coke can.
I'm not convinced I would want to use it on it's own in the pouring rain though. But only one way to find out I guess.

Thanks again. It was exactly I needed when I needed it.

Sounds great for the dollar

Definitely is. Even if just as an emergency one to throw in your bag.

great :)

I've got a crazy light summer bivvy already and a RAB Storm for the UK but I want something lighter, like one of the RAB eVent bivvies. Any suggestions? Anyone moving one on?

The best is Borah Gear, custom.

They have an eVent bivvy but it's not in stock on their site. Under 400g though.

Rab Alpine is

Wonder what material this stuff is made from, if it’s available by the meter............

It must be, coz that's how borah guy makes them.

Hmmmmm. Would be keen to see one for 5 minutes IRL, and see about making one. Could use an army biv as template. Pretty sure taping will be zero issue, stitching neither.

See a bivvy or the material?

Might not be easy to get although some people are using it small scale so someone must sell it.

Got army bivvies but they are oversized, interested in how the smaller ultralight ones are constructed. But yea, keen to maybe try make one if I can get the right material.

The lighter ones tend to be a bit more sculpted, like mummy bags, but they can't be too much smaller because they need to have space to allow sleeping bags to loft within them. So a lot of them are still just basic rectangles. Or do you mean, how are they stitched, specifically? I have no idea about that aspect of construction. I passed that class but my sewing was pretty bad. :)

Ahaha. Well as you have pretty much one of each ever produced, if/when you next grab one (any ultralight) out please could you take a couple pics of it laid out, and inside-out too and pm me please?

I have in my head how it must be constructed, but yea, interested to see the seams and the panels.

I sold my first two bags. I basically want something in between the two bags I have now so I think the Rab eVent Alpine or that Borah Snowy one are likely to fit the bill (I'd be keen to find other options though). It will likely be used with a new sleeping bag, maybe a sleep pad or my down jacket if I'm racing with it. Depends on weather obviously.

Email them, tell them exactly what you want, custom.
They will make it to your specs. They are extremely good and extremely well priced.
Lewis Ciddor, winner of TD, for example, uses one for racing and loves it.

Bivvies are ok but not having a proper shelter in winter is asking for trouble and hypothermia.

Well, no.

People have been successfully sleeping in bivvy during winter, especially on the top of a snow covered mountain.

Having said that, you'd need more gears to stay warm which a tent end up being lighter.

bivvying in alpine/winter conditions is not done by choice, by anyone...in the case of alpinists it's because they can't carry a tent and climb at the same time.
unless you are an experienced alpine climber don't take a bivvy to alpine/winter conditions

I bivvied out in the Beast from the East in a -10-rated bag. It was fine. My face was extremely cold though.

Would I have been better off with a tent? probably

My face was extremely cold

exactly

If the wind hadn't changed direction overnight, and I wasn't sharing a too-small tarp, it would have been fine I think. I've bought a balaclava, yet to try it in proper cold though

Well, a considerable amount of alpinists decided to sleep at the top by digging out a snow grave to allow them to put their bivvy in, simply so they can enjoy the night sky and morning sunrise.
