FLEXTAIL Zero R05 Mummy L inflatable mattress orange

The FLEXTAIL Zero R05 Mummy L is an ultralight inflatable sleeping mat designed for hiking, camping and mountain expeditions. With an R-value of 6.0, it provides strong insulation from cold ground, and the manufacturer rates it for comfort down to -18 °C, with a limit of -26 °C. Weighing 600 g and measuring 185 × 51 cm, it packs down small enough to fit easily in a backpack.

The ergonomic mummy shape reduces unnecessary surface area and keeps warmth close to the body. U-shaped air chambers distribute your weight evenly and offer stable support, while the roughly 10 cm thickness helps cushion you from uneven terrain. A multi-layer construction with an aluminium heat-reflective layer and insulating fill helps retain body heat.

The 20D Ripstop nylon shell with a TPU coating is light yet durable. A one-way valve makes inflating and deflating quick and easy. The mat is tested to the 4S standard and packs to roughly Ø13 × 23 cm.
