Engineered with precision to deliver exceptional warmth in a compact size, this insulated air mat is ideal for alpinists and adventurers exploring in winter conditions. With a heat-reflective TILT lining and air-trapping Stratus™ R insulation, it reduces heat loss through both radiation and convection, offering you a comfortable sleep on frozen bivi ledges and clear nights at altitude. Low on weight, high on comfort, it thrives on long-distance ski tours, winter fastpacking trips, and multi-day ascents.
- 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 versatile rectangular shape is comfortable whatever your preferred sleeping position.
