Functional Design® Summer sleeping bag Doubler will turn your single-person mummy bag into a roomy bag for two people. The Doubler allows you to create your own custom sleeping system: just zip the doubler into your current mummy bag and you only have to pack one sleeping bag. The Doubler provides almost five feet across the shoulders and hips and then tapers down to your shared foot-box. The Doubler can be used either on top of, or underneath your bag (an especially nice combination if you are using a down sleeping bag). Also, you can zip the Doubler into itself for a perfect child-size sleeping bag or bivy. The Summer Doubler was designed for bicyclists, kayakers, rock-climbers, backpackers, and families who love camping. The Summer Doubler is made with a full-length 70" YKK #8 coil separating zipper, 50 denier Ripstop Nylon, a single layer of Polarguard 3D insulation, and built in draft tubes along the zipper. The result is a highly compressible pie that is lightweight, breathable, absorbs little moisture and retains loft even when wet. The Sweetie Pie is easily stored and laundered, and is non-allergenic and mildew resistant. IMPORTANT UPDATED 2009 Compatibility issues: the Doubler is compatible with many mummy style sleeping bags made between 2000-2008 using a full-length YKK #8 coil separating zipper; this includes bags from Sierra Designs, North Face, Marmot, REI, and North Face. See our website for full list of compatible sleeping bags. The Doubler is NOT COMPATIBLE with any 2009 bags, or those which use a YKK #5 or # 10 zipper. [More]
