The Outdoor Research Helium Emergency Bivy is one of those items that you might hope you never need but are absolutely thrilled to have at the ready just in case. It weighs just 9.6 ounces, packs down small, and delivers waterproof/protective shelter for emergency situations.

The bivy has 84" x 36" in-use dimensions so you hunker safely inside it with or without a sleeping bag and sleeping pad. Its lightweight 30D Pertex Shield 2.5L nylon fabric is durable, breathable, and completely waterproof.
