Statut obtained by RAB at the Muule barometer

A very high-end model, the RAB Ultrasphere 4.5 inflatable mattress is intended for demanding users looking for the lightest possible solution without sacrificing comfort.
Ultralight and compact, it nevertheless provides excellent insulation ( R-Value of 4.3 ), notably thanks to TILT technology, a reflective film placed within the insulation reducing heat loss by radiation. Plus , 100% recycled Stratus™ R insulation traps air to reduce heat loss through convection , ensuring you're recharged to be strong the next day even if temperatures are freezing.
Showing optimal performance when used in combination with the Rab Mythic Ultra 120 Modular sleeping bag, this mattress with a length of 183 cm in this Regular version is suitable for people up to approximately 1m80. It has a generous thickness of 8 cm allowing it to cope with all types of terrain.
