Big Agnes Battle Mountain 3

The Big Agnes Battle Mountain 3 is a four-season dome tent for three people, developed with Himalayan climber Chhiring Dorje Sherpa and built for mountaineering and alpine use rather than standard three-season backpacking. The fly uses undyed Dominico polyester ripstop, chosen for tear strength and UV resistance — a fabric choice aimed at surviving high-altitude sun exposure and rough handling on exposed terrain over multiple seasons. At 3997 g packaged weight, it's a genuine expedition-weight shelter, not something you'd carry on a lightweight three-season trip. This is a tent for climbers and mountaineers heading above treeline into serious wind and snow load, sharing the space three-up on multi-day approaches or basecamp stays — hikers looking for a lighter three-season backpacking tent should look elsewhere in the range.
