Outdoor Research Helium UL Bivy

Sleep light, stay dry, and keep moving. The Helium UL Bivy gives you reliable shelter when your route takes you through exposed alpine ledges or damp forest floors in shoulder season. It packs down small, disappears in your kit, and sets up fast when weather rolls in, so you spend less time managing camp and more time enjoying the outdoors. When you need a low profile shelter that handles wet nights, shifting conditions, and tight bivy spots, this one earns its place in your pack.
