We’ve slashed weight and volume wherever we can with the Ultrasphere 1.5, crafting the definitive sleep mat for when every gram counts. It uses innovative offset air chambers to disrupt the flow of convection currents inside and trap heat, keeping you warm on wild overnights without the need for bulky insulation. Combined with a soft, exceptionally lightweight fabric, its weight-saving construction makes it ideal for summer bikepacking, thru-hiking, and multi-day mountain running.
With a comfortable tapered mummy shape that keeps things compact, 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, the Ultrasphere 1.5 is fully equipped for your multi-day trips where low weight and bulk are critical.

R-Value: 1.3
Your sleep mat’s R-value is an indication of how well it will resist heat loss. A higher R-value means it will insulate you more effectively from the ground underneath, and will be better suited to cold environments.
