The Rab Ultrasphere 5 Sleep Mat is an ultralight sleeping mat developed for fast and demanding tours where both warmth and light weight are crucial. Whether you're bikepacking, thru-hiking or multi-day running adventures in the mountains, it delivers an impressive warmth-to-weight ratio.
With an R-value of 5.5 and a weight of just 345 grams (Regular), Ultrasphere 5 offers reliable insulation well into colder conditions - without weighing down your pack. The construction combines two layers of heat-reflecting TILT technology, which efficiently transfers body heat, with offset air chambers that encapsulate heat and increase comfort without extra material.
The tapered mummy shape minimizes unnecessary bulk while providing good support, and with a thickness of 8 cm, you get a stable and comfortable sleeping surface even on uneven ground. The 20D material is both soft and durable, contributing to a comfortable feel throughout the night.
Inflation is quick and easy thanks to a two-way valve and included pump bag, so you can focus on recovering from long days on the move.
The Ultrasphere 5 is a thoughtful choice for those who want to move fast and light without compromising sleep comfort. One of the most heat-efficient options in its weight class, it's ready for everything from summer mountain hikes to chilly alpine nights.
