Bivys and liners

About

Cutting pack weight doesn’t have to mean compromising on comfort. One of the most effective ways to go lighter on overnight hikes or alpine missions is to leave the tent behind and use a bivy. Ultralight bivy bags offer a minimalist yet highly protective alternative — perfect for mountaineers, backpackers, and bikepackers who value simplicity and efficiency. Pairing a bivy with a tarp or floorless shelter gives you maximum flexibility to adapt to changing conditions, from high alpine ridges to forest trails. Many ultralight bivy sacks are crafted by small, innovative manufacturers dedicated to quality and performance.
