Rab Inflatable mattress Ionosphere 5

Both ultra-light, very warm, perfectly insulating and extremely compressible. The Ionosphere 5 strikes a balance between lightness and comfort, perfect for fast packing (multi-day hikes), thru-hiking (long-distance hiking on your own) or hiking in sometimes inhospitable environments. This self-inflating insulating mattress incorporates all the technologies needed to keep you warm when the temperature drops, thanks to its TILT thermo-reflective film and Stratus™ R insulation which helps reduce heat loss through radiation and convection. The result: an exceptional weight-to-heat ratio, allowing you to recharge your batteries in cold weather, even when your backpack needs to be as light as possible.
