Outdoor Research Bivys Helium Bivy

Why We Like The Helium Bivy

Tipping the scales at a feathery 18 ounces, the Outdoor Research Helium Bivy is ideal for moving fast through alpine terrain and wilderness expanses without excess weight slowing you down. However, don’t let its minimalist design fool you into thinking it’s lacking weatherproof performance or functional features. The Helium Bivy offers total waterproofing and maximum breathability with its Pertex Shield+ 2.5-layer membrane, TPU floor lamination, and fully taped construction. Ultimately, this means you stay pleasantly dry when you’re camping out in widely variable conditions, all without soaking in a sauna of built-up perspiration during humid summer months.
