Rab Storm Bivy

Ultralight protection for a dry night's sleep.

Don't get your ultralight down bag caught out in the rain—tuck it, and you, inside the Rab Storm Bivy and hunker down for a comfortable night's sleep. Hyperlite Storm fabric and fully taped seams ensure you stay dry when monsoon season rears its head. A mesh panel vent lets you get some ventilation to keep condensation down and keep things fresh.

Picture is deceiving.

  • Familiarity: I've used it several times

I bought this bivy sack for my first backpacking trip to Yosemite. Of the 5 nights I was there, I only slept it in 3 nights and I slept horribly because there was no headroom and the sack collapsed on top of my head. I felt like I was trapped in a trash bag and slept horribly. Now maybe I set up the sack incorrectly, but from what I could tell there was nothing inside the bivy sack to give it structure as it shows in the picture. I ended up sleeping in my friends tent because I couldn't take it anymore. The breathable vents are shielded by a flap that is velcro'd in place. The flap kept falling down thus making it more difficult for breathing.


-no head room
-not breathable

Rab storm bivy is great

  • Familiarity: I've used it once or twice and have initial impressions

This is a light, small bivy that easily adds 5+ degrees of warmth. Used it twice in Zion Nat'l Park. Once in dry conditions (slept with it unzipped all night) and once under a fall sprinkle where I stayed completely dry. Bottom material is durable which I like as I can put my sleep pad inside with me.

If you're on a budget this is a stellar deal and perfect for lightweight backpacking as well.
