Rab Ultrasphere 5 Sleeping Mat (Regular Wide)

When both warmth and low weight are crucial, the Ultrasphere 5 is the ultimate packable, featherlight air mat, honed for fast-paced exploring in demanding mountain conditions.

Using a groundbreaking design, the Ultrasphere 5 includes two layers of TILT (Thermo Ionic Lining Technology), a reflective film which boosts the mat's warmth-to-weight ratio. This technology reflects heat towards your body, reducing radiant heat loss for a fraction of a gram. This updated sleeping mat also features new offset air chambers designed to trap heat within its construction, allowing you to recharge comfortably without the need for high-volume insulation. The mat uses a comfortable tapered mummy shape that eliminates unnecessary bulk, while the soft, exceptionally lightweight 20D fabric feels comfortable against the skin for a distraction-free sleep. When it's time to pitch for the night, the two-way valve and inflation sack make camp setup quick and hygienic. Lastly, a roll-away stuff sack with a repair kit has been included for any mishaps whilst out on your adventure. Highly comfortable and supportive, the Ultrasphere 5 is the ideal foundation for thru-hiking, bikepacking, and multi-day mountain runs.
