Ultrasphere 4.5 Ultralight Sleeping Airbed

About the Rab Ultrasphere 4.5

Being ultralight and super-packable, with a cracking warmth-to-weight ratio, the Ultrasphere 4.5 from Rab makes the ideal all-mountain sleep mat.

The unbeatable benefit of this mat is that aside from being ultralight, it also packs down small enough to take on all your trekking, climbing and backpacking adventures. The warmth comes from the 2 layers of TILT reflective film which traps air and reduces heat loss. This helps to maintain your temperature when the mercury drops, helping you slumber well and wake up recharged and ready to go.

The Ultrasphere 4.5 also has a low-profile two-way valve and 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.

Constructed using 20D recycled polyester outer fabric finished with a fluorocarbon-free DWR, the Ultrasphere 4.5 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 for thru-hiking and multi-day mountain runs.
