For mountain expeditions where every gram matters, the Ionosphere 5 is ultralight and packable, yet loaded with the necessary tech to keep you warm in tough conditions. The TILT reflective film within the insulation reduces radiant heat loss, while the Stratus™ R insulation traps air to lessen heat loss through convection, ensuring you can recharge for tomorrow even when the temperature plunges.

The tapered mummy shape is economical on weight, keeping pack size to a minimum. Oversized outer chambers ensure you stay central on the mat as you sleep, and the soft-finish fabric features a graduated grip print to reduce sleeping bag slip during the night. Inflation and deflation are quick and easy thanks to the low-profile two-way valve and pump sack.

The Ionosphere 5 is built using 100% recycled insulation, recycled fabric and a fluorocarbon-free DWR, and offers a superb warmth-to-weight ratio which won’t hold you back.
