About the Rab Ionosphere 5 Regular

What is the Rab Ionosphere 5 Regular Sleeping Mat good for?

Engineered for demanding alpine environments, the Ionosphere 5 delivers warmth retention through TILT reflective film and Stratus R synthetic insulation with compact and lightweight carry for weight-conscious expeditions. Optimised for hikers and alpinists who demand reliable thermal performance without excess bulk, the Rab Ionosphere 5 fuels three-season adventurers across spring, summer and autumn conditions with a balanced warmth-to-weight efficiency.

How will some of the key features of the Rab Ionosphere 5 Regular Sleeping Mat enhance my experience?

The TILT reflective film within the insulation reduces radiant heat loss whilst maintaining lightweight construction for cooler-weather performance. In addition, Stratus R synthetic insulation traps air efficiently, delivering consistent thermal protection during cold nights. Furthermore, the air-and-insulation construction ensures superb warmth-to-weight ratio whilst achieving minimal pack dimensions of 23x11cm for streamlined expedition packing. The mat also features oversized outer chambers that keep you centralised during sleep whilst the tapered mummy shape saves critical weight for demanding ascents.
