Rab Stratosphere 4 Insulated Sleep Mat

About the Rab Stratosphere 4

Being nice and light and super-packable, with a cracking warmth-to-weight ratio, the Stratosphere 4 from Rab makes the ideal all-mountain sleep mat.

The big benefit of this mat is that aside from being highly insulating, it also packs down small enough to take on all your trekking, climbing and backpacking adventures. The warmth comes from the recycled Stratus™ R insulation, which traps air and reduces heat loss. This really helps to maintain your temperature when the mercury drops, helping you slumber well and wake up recharged and ready to go.

The Stratosphere 4 also has a low-profile two-way valve and comes with a super-useful pump sack, so it’s quick and easy to inflate when you’re ready to hunker down. There’s a repair kit thrown in too, which is always a bonus.

Perhaps most importantly, this mat is a comfy one. The oversized outer chambers keep you in the middle so there’s less risk of rolling off in your sleep, while the roomy rectangular shape makes for 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 4 is better for the environment too. All in all, this is a rugged and reassuring sleep mat you can trust to keep you comfortable, warm, and well-rested whatever the season.
