Mattresses Ionosphere 5

For mountain expeditions where every gram counts, the Ionosphere 5 mattress is ultra léger and compact, yet packed with the technology to keep you warm in extreme conditions. TILT reflective film within the insulation reduces radiant heat loss, while Stratus™ R insulation traps air to reduce convective heat loss, ensuring you recharge the batteries to be fit the next day even if temperatures are freezing.

The tapered sarcophagus shape saves weight to minimize the size of the sleeping bag. XXL outer compartments ensure that you stay right in the center of the mattress while you sleep, and the soft-finish fabric features a non-slip print to prevent the sleeping bag from slipping during the night. It inflates and deflates quickly and easily thanks to the discreet two-way valve and pump bag.

The Ionosphere 5 mattress is made with fully recycled insulation, recycled fabric and a durable fluorocarbon-free water-repellent (DWR) finish, and offers an excellent warmth-to-weight ratio that won't disappoint.
