Bivouac sleeping bags

A lightweight and compact emergency shelter 

When tackling demanding mountaineering routes or multi-day treks, a bivouac sack (or bivy bag) is an indispensable safety item. Designed as a waterproof and windproof shell to be used over your sleeping bag, it protects you from moisture, wind, and sudden cold without the weight and bulk of a traditional tent. It is the perfect solution for planned minimalist bivouacs, as well as an essential safety item in your pack for any high-altitude emergency.

High-quality waterproof and breathable materials  

At Alternativa Sport, we offer bivy bags made with highly breathable and waterproof technical membranes, preventing external water from penetrating while facilitating the evaporation of internal condensation to ensure a dry sleep. Lightweight, packable, and incredibly tear-resistant against rocks, our models are made by the leading outdoor brands. Choose maximum safety for your nights under the stars.
