Black Diamond Big Wall Hooped Waterproof Bivy with Integrated Waterproof Tie-in Point

This bivy sack is an in improvement over what I have used in the past. It is fairly well sealed. I have only used it a couple of times under light rain, and it kept me dry, but I am not sure how well it will perform under heavy rain. I can easily fit my minus 20 sleeping bag in it so I am planning to use it this winter. It is true that the opening is a little small but that is the trade-off to get more protection. It is probably the best bivy sack I have had.

I've spent several nights in this and it is bomber. It is really roomy which is great for keeping some stuff like boots and other gear in with you. If you manage the ventilation there is little condensation. I haven't been in a situation that required the sack to be completely sealed so I'm sure there would be a little moisture on the inside which is normal. The opening is a little small so it's kind of awkward to get in. I never really liked the bivi sacks I've used before but this has replaced my tent for a lot of my adventures.

slept very warm in 10 degree weather directly on snow. Didn't feel claustrophobic at all. I'm not a good sleeper, but I was out at 10pm and woke up at 7:30am completely rested. And it weighs nothing! I love this product.
