Rab Ionosphere 5.5 Sleeping Mat

The Rab Ionosphere 5.5 Sleeping Mat is built for winter adventures where staying warm through the night really matters. It uses reflective TILT technology and Stratus™ R insulation to trap heat and reduce loss through both the ground and cold air inside the mat. Despite its impressive warmth, it stays lightweight and packs down small, making it ideal for ski tours, winter fastpacking, and alpine bivis. A dependable option when you’re camping on frozen ground or high, exposed ledges.

Details: 
- 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.
- Inflation and deflation are quick and easy thanks to the low-profile two-way valve and pump sack.
