Exped Dura 10R LW is a down-insulated sleeping mat built for extreme cold and demanding winter expeditions. With an R-value of 10 – among the highest on the market – it provides maximum insulation against cold ground, making it ideal for alpine expeditions, winter camping on snow and ice, or for those who feel the cold easily at night.

The insulation is based on Exped's tried-and-tested DOWNMAT TECHNOLOGY with 700 cuin RDS-certified down, delivering a superior warmth-to-weight ratio. Each air chamber contains a down baffle divided into three sections, preventing the down from shifting and ensuring even insulation across the entire mat. The Cradle Comfort construction, with slightly raised outer chambers, keeps you centred on the mat throughout the night, while 10 cm of thickness provides comfortable cushioning against uneven ground.

The LW size (Long Wide) measures 197 × 65 × 10 cm and offers extra room in both length and width – ideal for tall people, side sleepers, or anyone wanting a little more comfort at night. The shell is made from soft and durable recycled polyester (75D on top, 175D on the bottom), bluesign-approved and PFAS-free.

The mat features two FlatValve valves – one for inflation and one for deflation – making setup and packing quick and straightforward. Supplied with a Schnozzel pump bag for fast, moisture-free inflation, as well as a repair kit. Weight: approx. 1329 g.
