Designed for expedition use and nights high on the trail, the Rab Stratosphere 5.5 Sleeping Mat delivers outstanding warmth in a lightweight package. With an impressive warmth-to-weight ratio and R-value of 5.5, it’s a highly versatile all-mountain mat built for trekking, climbing, and backpacking trips across the seasons.
At its core, the Stratosphere 5.5 features recycled Stratus R insulation, engineered to trap air and minimise heat loss from convective currents, helping you stay warm as temperatures drop and ensuring you wake refreshed and ready for the next day’s challenges. The mat’s 8cm thickness provides excellent insulation and cushioning from cold ground, while oversized outer chambers keep you centred throughout the night. This, combined with its generous width and hybrid rectangular shape, offers plenty of space to stretch out and sleep naturally in any position, ensuring a comfortable, undisturbed rest.
The recycled outer fabric with an internal TPU coating is finished with a fluorocarbon-free DWR to repel moisture and condensation, even on damper nights. Inflation is quick and effortless thanks to the low-profile two-way valve and included pump sack, allowing you to set up camp efficiently at the end of a long day. Whether you’re bedding down after a long summit day or preparing for an early alpine start, the Stratosphere 5.5 helps you rest well and wake ready for your next adventure.
