Ultralight yet super warm, highly insulated yet extremely packable. The Ionosphere 5 offers the perfect balance of low weight and comfort for fastpacking, thru-hiking, and multi-day mountaineering in challenging environments. This insulated air mat is equipped with all the tech to keep you warm when the temperature drops, with a combination of heat-reflective TILT and Stratus™ R insulation to reduce heat loss through radiation and convection. The result is an exceptional warmth-to-weight ratio, allowing you to catch vital rest in cold conditions, even when pack space is at a premium.

The TILT reflective film inside the mat reduces radiant heat loss, boosting warmth for weight.
Stratus™ R insulation traps air to prevent heat escaping through convection.
Soft-touch, lightweight 20D fabric on the upper mat, with a 30D base for added durability on rough ground.
Oversized outer chambers to keep you central on the mat.
The tapered mummy shape is economical on weight and minimises pack size.
Inflation and deflation are quick and easy thanks to the low-profile two-way valve and pump sack.
R-value: 4.8.
Thickness: 8cm.
Roll-away stuff sack with repair kit included.
Dimensions: Regular 183x51cm. Large 196x64cm.
