Rab Ionosphere 5 Sleeping Mat

Designed for alpinists and mountain expeditions, the Rab Ionosphere 5 Sleeping Mat delivers the perfect balance of lightweight packability and reliable warmth, making it ideal for fastpacking, thru-hiking, and multi-day mountaineering in challenging environments. Thermo Ionic Lining Technology (TILT) is a heat-reflective fabric designed to reduce heat loss from the body, working alongside Stratus R insulation to trap warm air, retain warmth when wet and dry quickly. Together, they provide an impressive warmth-to-weight ratio andR-Value of 4.8, making this sleeping mat ideal for overnight use on cold ground, allowing you to rest comfortably even when pack space is limited.

A soft-touch 20D recycled polyester upper keeps pack weight to a minimum, while the 30D recycled polyester base adds durability for rough ground and repeated mountain use. The 8cm thickness offers excellent insulation and comfort, with oversized outer chambers helping to keep you centred throughout the night. Finished with a tapered mummy shape, low-profile two-way valve, and supplied with a pump sack, stuff sack and repair kit, this packable air mat is built for fast-moving, lightweight adventures.
