Sleep, even when things go south.
You never really plan on spending a cold, wet, and windy night out in the open, but the Rab Survival Zone Bivy Sack is designed to provide lightweight emergency shelter when things don't quite go according to plan. It weighs less than a pound and packs down to the size of a water bottle, so it's easy to stash in your pack when you head up into questionable conditions in the alpine, and it's made from 70D Hyperlite Storm fabric that blocks water so your bag doesn't get soggy and cold. A drawstring entrance seals up tight to prevent water creeping in around your face, too, so you can sleep (relatively) comfortably when things don't go the way you expected them to.

Thin, but works well
- Familiarity: I've put it through the wringer
I am a wilderness field guide, and used this bivy in Utah this winter and was super impressed. Doesn't provide maybe some of the warmth of other more thick bivies, but this one ROCKS. It packs well, keeps you dry, and is a good price. I swear by this thing.
Would this work as a sleeping bag cover to protect my down bag from condensation on tent / tarp walls?
