Rab Stratosphere 4 Sleeping Mat – Regular/Wide

Designed for nights outdoors, in mountain huts, or high on the trail, the Rab Stratosphere 4 Sleeping Mat delivers dependable warmth in a lightweight, compact design. With an excellent warmth-to-weight ratio and an R-value of 3.8, it’s a versatile mat for trekking, climbing, and backpacking year-round.

At its core, the Stratosphere 4 features recycled Stratus R insulation, designed to trap air and minimise heat loss through convection, keeping you warm as temperatures drop. The recycled polyester outer fabric with internal TPU coating is finished with a fluorocarbon-free DWR, repelling water and condensation.

A low-profile two-way valve and included pump sack make inflation quick and easy, so you can set up camp with minimal effort. Oversized outer chambers keep you centred on the mat through the night, while the generous rectangular shape offers plenty of room to sleep comfortably in any position. Whether you’re bedding down after a long summit day or settling in for an early alpine start, the Stratosphere 4 helps you rest well and wake ready for your next adventure.
