Rab Ultrasphere 4.5 Sleeping Mat in Dark Pewter

Season:Always In Stock

Brand:Rab

Code:QMA-06-DPW

When both warmth and low weight are crucial, the award-winning Ultrasphere 4.5 is the ultimate packable, featherlight air mat.

Its ground-breaking design includes two layers of heat-reflective TILT, which reduce radiant heat loss, and offset air chambers that trap heat within the construction, allowing you to recharge comfortably without the need for high-volume insulation. Combined with a soft, exceptionally lightweight fabric, the mat’s weight-saving construction makes it ideal for bikepacking, thru-hiking, and multi-day mountain running.

With a comfortable tapered mummy shape that eliminates unnecessary bulk, the mat is thick and supportive, so that you can catch vital rest and restore the energy reserves needed for your action-fuelled days on the trail. When it’s time to pitch for the night, the low-profile two-way valve and inflation sack make camp setup quick and easy.

Featuring an included repair kit and unrivalled warmth-to-weight ratio, the Ultrasphere 4.5 is honed for fast-paced exploring in demanding mountain conditions.

While compatible with any sleeping bag, the Ultrasphere 4.5 can be paired with our Mythic Ultra 120 Modular bag to form an ultralight sleep system weighing under 700g.
