The recycled Stratus™ R insulation is designed to trap air and reduce heat loss through convection. The mat features a low-profile two-way valve and comes with a handy pump sack, so it’s quick and easy to inflate. Oversized outer chambers keep you in the center of the mat and stop you rolling off in your sleep, while the spacious rectangular shape will ensure a comfortable night’s rest whatever your preferred sleeping position. Constructed using 100% recycled insulation and recycled outer fabric finished with a fluorocarbon-free DWR, the Stratosphere 5.5 is a robust and reliable sleep mat which you can depend on to keep you comfortable, warm, and well-rested throughout the seasons.
