I need your help. I’m working with a mountaineering guide on designing a Bivvy sack and I need your feedback.
What is a bivvy?
First off, for those that don’t know, a bivvy or bivouac is a bag to go over sleeping bag. It can be mesh to keep the bugs away or waterproof or resistant for inclement weather. It’s designed for solo hikers. It’s often used with a small, light-weight tarp.
