Familiarity: I've put it through the wringer
Being light as hell, compact and relatively inexpensive I couldn't find a better bivy for my needs. Great for backpacking or sleeping at the base of a climb for an early start. This bivy has gotten me through a couple of light Sierra summer storms and held up great. Not sure how it'll do in heavier weather but I'm sure it would perform well. The bug mesh and single pole make this bivy very livable and help with moisture control. Sure you can go with out the pole to save weight but you'll wake up with a wet face. I highly suggest this product to anyone needing a lightweight compact shelter.
