Outdoor Research Helium Bivy

Why We Like The Outdoor Research Helium Bivy

The Outdoor Research Helium Bivy may not actually be lighter than air, but it comes about as close as any shelter can. This ultralight bivy weighs just over a pound, making it a favorite of thru-hikers and bikepackers looking to shave ounces and minimize the size of their pack. The Pertex Diamond Fuse membrane offers complete waterproof protection while maintaining breathability to minimize condensation inside. The single-pole design allows us to set it up in a flash, and we can customize our ventilation with the mesh window above our head that can be pulled shut using the two internal fly fasteners.
