Rab Ionosphere 5 Sleeping Mat

The Rab Ionosphere 5 Sleeping Mat is all about delivering serious warmth in a lightweight, easy-to-pack design. With heat-reflective TILT working alongside Stratus™ R insulation, it reduces heat loss from both radiation and airflow inside the mat to keep you warmer through the night. It strikes a smart balance between comfort, insulation, and minimal pack size, so you can travel fast without sacrificing sleep. Perfect for cold-weather fastpacking, thru-hikes, and alpine missions where every inch of space counts.

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 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.
