Ultrasphere 4.5 Sleeping Mat

The Ultrasphere 4.5 stands out as the ultimate packable and featherlight air mat, prioritising both warmth and low weight. This award-winning mat boasts a groundbreaking design with two layers of heat-reflective TILT, effectively reducing radiant heat loss. The offset air chambers trap heat within the construction, eliminating the need for high-volume insulation and allowing for comfortable recharging. Crafted from a soft and exceptionally lightweight fabric, the mat's weight-saving construction makes it ideal for activities such as bikepacking, thru-hiking, and multi-day mountain running.

Its comfortable tapered mummy shape eliminates unnecessary bulk while providing thickness and support for essential rest and energy restoration during action-fueled days on the trail. Setting up camp for the night is a breeze with the low-profile two-way valve and included inflation sack. Tailored for fast-paced exploration in challenging mountain conditions, the Ultrasphere 4.5 comes with an included repair kit and offers an unrivaled warmth-to-weight ratio.
