Alpine Bivy

Outdoor Research equipped the two-pound Alpine Bivy with waterproof breathable Gore-Tex Respiration Positive to keep you comfortably dry while backpacking in wet weather. Gore-Tex's Respiration Positive provides more breathability than standard Gore-Tex membranes, giving you more comfort throughout the night. Outdoor Research's Hydroseal Floor and fully taped seams further prevent snow and rain from seeping through.

When it stops snowing and raining, the Alpine Bivy unzips to reveal a no-see-um mesh window for ventilated airflow and bug protection. There are straps inside to secure your sleeping pad, and an internal mesh pocket stows your alarm clock, smartphone, or GPS watch. Outdoor Research included five stake loops, a loop for a guy line, and a Delrin pole that you can either use for more headspace or leave at home to save weight.

The Bomb

If you're looking for something lightweight, compact and able to stand the test of time this bivy is just what you need! My husband has been using his for years and it's still in great condition. He's 6'2" and the length is great for him. Width/height is great for most pursuits but with a 4" Big Agnes sleeping pad, accordion pad, several layers of clothing and a 0 degree bag it can be a little snug. Slimmer sleeping pads should work out great in terms of space! Pros: -Lightweight -Packs down small -Indestructible -Protection from the elements Cons: -Not for the claustrophobic

Thank you so much, Renee! Leta OR Rep

Have You Truly Slept in the Outdoors?

I've put it through the wringer

I was at the climbing gym the other day and said to my partner "I'm never sleeping in a tent again." The woman climbing next to us decided to not only eavesdrop, but also jump into our conversation. "How could you do that?! Camping is so great and especially out here in Utah!" she said. I looked at her with a smile. "Well, have you ever slept in a bivy?" I asked. This woman thought I was quitting on nature altogether. I'm simply calling it quits with tents. She had no idea what a bivy is. Not only are bivy's lightweight, easy to pack, and waterproof, but they allow you to truly sleep outdoors. I've slept through 5 degree nights in inches of snow and cool, fall nights in the west desert. A bivy is easily the most mobile, lightweight, simplistic way of comfortably camping in the elements. It allows you to cowboy (or as I like to say, cowgirl) camp indefinitely. I love this bivy and it's advancement's towards sleeping under the stars, all year long.

Thank you Moriah!! Leta OR Rep
