The Ortovox Bivy Double comes in handy for big adventures whether you and a partner were planning on staying the night or not. It's a great option for ultralight backpackers and emergency-prepared connoisseurs alike. Windproof, water-resistant material helps you stay the night comfortably, and it's durably abrasion-resistant so you can use it on more than the occasional emergency situation. Ortovox included a compressible stowaway bag for compact packing.
