Why We Like The Alpine Bivy

When we're planning on sleeping in tough conditions but aren't interested in carrying a tent, we make sure to stick the Rab Alpine Bivy in the pack first. It weighs only a pound and packs down to the size of a water bottle, so we never have to leave essential gear out of our pack to bring it along, and it zips up all the way to offer full protection from the alpine elements. The eVent  waterproof and breathable membrane and 3-layer DVStorm fabric keep water out and prevent condensation from building up inside, while the tough nylon floor stands up to rough ground when sleeping in less-than-perfect conditions.


  • Minimalist bivy for use on alpine expeditions and summit attempts
  • Waterproof, breathable construction fends off alpine precipitation
  • Mummy shaped to fit technical sleeping bags without losing warmth
  • End zip entrance with protective storm flap adds protection
  • Coated nylon bathtub floor prevents your butt from getting soaked
