It's back! The Basin + Range Bivy Suit turns a sleeping bag into something to wear around camp. We wrapped a nylon shell around 120 GSM synthetic insulation from ankle to hood, holding warmth right where a dying fire can't reach anymore. It's built for the hours after dark, when the temperature drops fast and the last good option isn't always the tent. What Our Gearhead(R) Experts Are Saying:"I've stopped changing before I get up to grab more firewood. The two-way zip vents the suit when it gets too warm inside and drops low enough that a middle-of-the-night bathroom break doesn't mean crawling all the way out of it."
