enshroud yourself in this cocoon
This bivy sack is phenomenal. light, dry. Just Used it first time in snow at around 8000 ft, temps in single digits to teens. Some very light condensation inside on awakening but otherwise very dry and does add warmth. Came with a tube of seam sealer so I meticulously sealed all seams although that may be unnecessary. Im 6'1 got the long and have plenty of room in the bottom for boots and other necessary gear and although it is somewhat snug I could still move around when needed. Tie in point looks bomber but didn't need it. Overall impressed
Almost completely happy.
Nice and light. Much more fun to carry then a tent. The pole that keeps the hood up is actually a thick wire that can be bent into all sorts of positions depending on the protection needed. Entry was not all that easy. I'm 6'1" @ 185lbs and with a NeoAir pad inside it was a task that will require some gettin used to. Keep in mind though the Neo is a large and does take up a good bit of space. Once inside space is not a problem. Just don't expect to have the full freedom of motion like one would have in a tent. Felt very comfortable and the bivy doesn't weigh down on you. No moisture at all. Not a drop. This would be 5 stars if entry was a lil better. I think my tents are goin to be seeing alot more closet time.
The Black Diamond Big Wall Bivy on Mount Rainier...
First bivy i've ever bought and im definitely not disappointed. Kept me warn and dry climbing 14ners and trekking in Montana. Can't wait till this winter to give it a real work out

Outstanding performance especially in winter.

The best of its class and very breathable
I have spent some good time in many different bivies but none can compare to this one. Extremely breathable and totally waterproof. A very durable fabric and the tie-in points are an important feature when needed. Not too tight or too wide, just right. A minimalist bivy with some breathing room. Only complaint is not as durable as some other fabrics but will hold up to tons of abuse.

Yes we can ship over seas, Unfortunately black Diamond is one of the restricted brands in which we can not ship out of the country. We have many other items in which we can ship over seas though and we would love to help you in any way we can.

Taped but not sealed.
I've used this bivy a few times now. I...
I've used this bivy a few times now. I realize condensation is general problem, but has anyone had problems with water build up (from condensation) at the feet? This water build up tends to get my feet wet and I start losing temperature. Know of ways to prevent this kind of problem?
Only option is to open the vent a bit more so your breath goes out.
Yeah, I have that zipper as wide open as it can go. I have the hood as up as possible. On nights that aren't too cold, I even sleep with my head outside. And I still get wet down at the feet. Maybe my feet are just super juicy...
Jared, I honestly haven't had much moisture in mine. Certainly not enough to draw heat from my feet. That would certainly be a bummer. Perhaps you know of this trick already but have you tried the Nalgene water bottle in the bag trick? If not, this is what you do. Pour not quite boiling water in a Nalgene bottle and throw it in the foot of your bag about an hour before turning in. It works great! I know the thought of a leaky water bottle sounds a bit risky and when my backcountry skiing buddy promised me it would work I tried it. Amazing thing is - the bottle is still warm when you wake up. This hasn't failed me yet and I've done it about 1/2 dozen times when I was cold enough. Screw on the lid tight and test it and you should be fine. Maybe if your feet are just "super juicy" it will still ward off the suck-i-ness of cold feet and the misery of losing badly needed sleep.
Jared, this may sound strange, but try some neoprene socks and if that doesn't work, try a full on vapor barrier liner. The water bottle trick above won't work because that will just create more condensation by making you even hotter. The problem isn't a temperature problem, it is a condensation problem that then translates into a temperature problem. If you have a down bag, this will only get worse the more nights you camp. Hope this helps.
Hello all, it seems to me that for a bivy...
Hello all, it seems to me that for a bivy that weighs in under 2 pounds this has a fairly large advertised packed size. 6x13" isn't that much smaller than my kelty 2 person tent. Can anyone attest to this tent being more compressible, or is that size limited by the length of the wire in the hood? Also if anyone could comment on how easy this is to get in and out of, and what sort of sleep systems you set it up with, i.e. do you bring a sil tarp to cover the head area or pitch to put gear under or change under. My backpacking in the north cascades of Washington usually involves obscene amounts of rain, I'm just trying to stay dry.
It would be difficult to get this more compressable. The hoop in the hood is not a factor. I've had two of these. I will buy a third if I have to although I doubt it as it's pretty durable. (My brother took my first one.) To answer your first question it's not the easiest to get in and out of - it's not the hardest either. With a little practice the middle of the night wiz isn't any worse than getting out of a warm tent. The hoop keeps the fabric off your face and I like that. And it creates a vent - which I really like. I've never used any tarp to cover the head area as it's un-necessary - to me. I've actually sat in this and ate dinner. (The hoop helped that) I got the long to store my shizzle in when it rains or starts blow'n. I've logged WAAAAAY more time in this than my tent in the past ten years which is a testiment to the ease and weight of this bag. I've used this for winter alpine ascents, back-packing, climbing and even quite a few car camps. I love this thing. Oh, and I've not had a drop of moisture from the inside or out.
That amazes me that people claim to not get any moisture...I get quite a bit! And I keep the zipper open. This is blowing my mind. From my point of view you'd definitely want a tarp or something if it's going to be raining or whatever (unless you have some other kind of shelter). Otherwise water will get in since you have to keep the zipper open (I can't imagine how much moisture would be inside if the zipper was closed). I personally take along a small tarp when I expect bad weather. But in my case it's usually just to aid in fast snow trenches in bad weather. So no rain so far, just snow (and not slushy snow). As far as the packed size goes, I hear you about your issue with the size. There are ways to compress it more, but the limiting factor is definitely the wire hoop. If it wasn't there, this thing would pack super small. But once again, it depends how you pack it as far as how compact it will be. And for the small opening, I think it's easy to get in and out.
In further response to your question about packability, I have recently begun to remove the delrin rod (hoop)and it does pack down quite a bit smaller. I just put the rod in my wand pocket on the side of my pack and carry it that way. This has two benifits. As I said, it allows you to pack it smaller but also helps keep the Delrin from retaining too much of a undesirable shape. It has been my experience that by packing the bag in the same fashion my rods arch flattens and is more difficult to bend back into a desirable shape when you're cold and tired and just don't want to mess with it. Delrin is a plastic that has memory so you can bend it, hold in that position and it stays. You can also straighten it which is how I like my rod so when I put it back in I get the desired arch and the fabric is kept off my face even with an improvised pillow.
Also, I just experienced my first bit of condensation on a recent Sierra trip but I had closed the zipper about 3/4 shut to keep out a cold blowing wind at around 13,000 feet. But, to me, the level of moisture was negligable (not appreciably wetting my down bag) Hope this helps.

How does this compare to the BD Winter Bivy?
This bag is waterproof (ToddTex and completely seam taped), and the Winter Bivy is not. The EPIC coating in the Winter Bivy is more breathable than Gore-Tex (or ToddTex I think), but not waterproof.Big Wall:Packed Weight- 1lb 12oz (805g)Packed Size- 6in x 12inArea- 15sqft (90in x 35in)Fabric- Canopy (ToddTex); Floor (PU Laminated)Winter:Packed Weight- 9.9oz (280g)Packed Size- 3in x 5inArea- 14sqft (85in x 35in)Fabric- Canopy (EPIC); Floor (EPIC)
