The Rab Ionosphere 5 Sleeping Mat is an insulated sleeping mat built for extreme winter conditions and minimal weight. With a smaller pack size than the 5.5, it features a tapered mummy shape to minimise bulk in your pack. Like the bigger model, it's made for extreme winter conditions but will better suit alpinists and mountaineers who prioritise minimalism.
