Rab Ascent Bivy

Weighing just over a pound and made with an eVent shell, the Rab Ascent Bivy will keep you dry on unplanned nights out or ultralight trips, even when the weather is some of the worst you'll encounter. The 3 layer eVent membrane repels wind, rain, sleet, and snow, but is also air permeable, which allows perspiration and moisture vapor to escape the ePTFE membrane, so you stay dry from both the inside and out. Rab gave the Ascent a wide sleeping bag profile to accommodate sleeping bags of all shapes and sizes, and added a removable no see um mesh zip door so you can let off a little steam or take a peak to see what that noise on the edge of camp don't worry, it's probably just a bear.
