Product Description 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. R-Value Your sleep mat’s R-value is an indication of how well it will resist heat loss. A higher R-value means it will insulate you more effectively from the ground underneath and will be better suited to cold environments. TILT (Thermo Ionic Lining Technology) A radical, heat retaining tech that works like an emergency blanket reflecting heat back towards your body, while maintaining breathability and comfort. Boosting thermal efficiency, it keeps you warm when the temperature plummets. Stratus™ R Resilient synthetic insulation developed with 100% recycled post-consumer material. Designed to trap the maximum amount of air possible, Stratus™ R boasts superior warmth for its weight, retains warmth when wet, and dries quickly. Fluorocarbon (PFAS) free product PFAS-free means Rab have phased out all intentionally added PFAS and are compliant with current EU and US legislation. FEATURES 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. Roll-away stuff sack with repair kit included. SPECIFICATIONS Weight: 470g/16.6oz (Reg) Dimensions: Regular 183x51cm. Large 196x64cm. Packed size: Regular 23x11cm. Large 28x12cm. R-value: 4.8.
