The Rab Stratosphere 5.5 Sleep Mat boasts a superior warmth-to-weight ratio, making it a versatile all-mountain sleep mat which is highly insulating yet has a small enough pack size to take on all your trekking, climbing and backpacking adventures. The recycled Stratus™ R insulation is designed to trap air and reduce heat loss through convection, helping to maintain your temperature when the mercury drops and ensuring you recharge ready for tomorrow’s challenges.

The mat features a low-profile two-way valve and comes with a handy pump sack, so it’s quick and easy to inflate when you’re ready to hunker down for the night. Oversized outer chambers keep you in the centre 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.
