Our UltraLite Alpini Bivy Sack is inspired by the elite Italian Alpine Corps. Formed in 1872, the Alpinis are the oldest active mountain infantry in the world, and to this day they are among the best trained and equipped mountain troops anywhere.

The Brooks-Range Alpini is serves as a super-light, one-person bivy bag, with or without a sleeping bag. Cut large enough to accommodate most standard length sleeping bags, the Alpini is constructed in an ultralight, waterproof/breathable ripstop outer fabric specially designed and fabricated for Brooks-Range. The floor of this lightweight shelter is completely waterproof, made of durable coated ripstop nylon. A short zip simplifies entry, along with a deep cowl-cover over the head with an elastic drawcord closure. Highly compressible, the Alpini packs to half the size of a one liter bottle.

"When you need an extremely lightweight, compressible shelter, the UltraLite Alpine Bivy Sack is the ideal choice." - WMB

Brooks-Range UltraLite Fabric™
The Brooks-Range UltraLite fabric used is specially designed for Brooks-Range UltraLite products. This air-permeable, water-resistant ripstop nylon is incredibly strong and resilient for its weight! We believe ours is the lightest water-resistant, fire retardant-treated fabric available for this use. The Brooks-Range UltraLite fabric has an impressive strength-to-weight ratio and ability to withstand wind shear. The fabric's custom coating keeps the fabric waterproof to a pressure of 1 pound per sq inch (2 ft water pressure depth), which exceeds the pressure generated by a driving rainstorm. Due to the fabric's custom coating, it does not absorb water and the coating will not wash or peel off as it is impregnated into the nylon fabric. With use, the Brooks-Range UltraLite fabric will soften and become more pliable. Certain types of dry desert sand will stick. The Brooks-Range UltraLite fabric is highly flammable,so keep it clear of direct flames and all heat sources.

Made using the Brooks-Range UltraLite 20-denier rip-stop nylon fabric. Unique integrated clam-shell storage stuff bag included. Untaped. Please Note: This is a sub-zero bivy bag, not suitable for use in sustained rainfall or wet conditions. Made in USA
