USGI BiVy Cover — Waterproof Breathable Outer Shell. Replace or Add to Any Sleep System.
A standalone USGI-style waterproof/breathable BiVy cover — drop it over any compatible sleeping bag to add weather protection, replace a worn-out original BiVy, or use it as an emergency one-piece bivouac shelter on the ground. Available in 5 military camo patterns.
⚠️ BiVy Cover Only: This is the outer waterproof shell only. No sleeping bags included. Pair with USGI-style modular bags or any compatible sleeping bag.
• Standalone Replacement / Upgrade
Sold as the outer BiVy shell only — drop it onto a USGI Modular Sleep System bag, an existing sleeping bag setup, or use it as a minimalist solo shelter.
• Waterproof + Breathable Construction
Outer fabric sheds rain, snow, and ground moisture while breathable membrane lets body vapor escape — stay dry sleeping on wet ground without trapping condensation inside.
• Sleep on the Ground Without a Tent
Built to be used as a one-piece bivouac shelter — pull the hood closed, climb in with your sleeping bag, and sleep through bad weather without setting up a tent.
• Compact Pack Size
Stuffs down small for rucksack carry — pack it as an emergency weather layer for any overnight field kit.
• 5 Military Color Options
UCP (Universal Camouflage Pattern) / OCP / Woodland / Camouflage / Olive Drab — match your loadout or terrain.
