One of the best ways to cut weight when overnight hiking or mountaineering is eliminating a tent. A bivy bag is an excellent alternative to a heavy tent. That's why bivy bags become popular among mountaineers and ultralight backpackers or bikepackers as well. The combination of a tarp or lightweight floorless shelter with a bivy is a great option for hikers who are looking for a lot of flexibility from their shelter. The ultralight bivy sacks are often hand-made by smaller gear manufacturers.
