Pro Bivy

When MSR set out to build the ultimate Pro Bivy, they enlisted the help of professional mountaineers to get it right. The result? An ultralight, quick-pitch bivy that fits between rocky outcroppings and withstands raging mountain weather. With ripstop nylon, full waterproofing, and breathable fabric, you can sleep well knowing you're protected from the elements before setting out on another day of testing your physical and mental capabilities in the alpine. And while you're chasing your objective, the bivy packs down to the size of a water bottle and weighs less than a pound so you can continue your light-and-fast mission on the mountain.

  • Ultralight professional bivy for major mountain objectives
  • Ripstop nylon floor stands up to rocky outcroppings
  • Breathable rainfly fabric reduces condensation
  • Quick-pitch gets you out of the elements
  • Waterproof coating lasts 3x longer than standard coatings
  • Packs up smaller and lighter than a water bottle
