Frontier Issue Bivy

The Frontier Issue Bivy is for the night you did not pack a bag. It is a windproof, heat-holding emergency sack — not a camp sleeping bag — so you can get off the wet ground, hold what warmth you have, and wait for daylight or a ride. It stuffs to a fist-sized pouch with a whistle on the drawcord: one pocket in the pack, next to Frontier Aid, not a bulky roll you leave at the truck. Being prepared is the point: if the hike runs past dark, you have a way to stay in place without turning a long day into a cold one.
