Rab Ultrasphere 4.5 Mat – Long Wide Sale

Ideal for These Activities: Expedition, Fast & Light Adventures, Mountaineering, Trekking

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.
