The Ultra 10R is characterized by the best thermal performance within the Ultra series and was developed for adventures in the coldest temperatures. The mat offers maximum insulation and a compact pack size for winter backpacking, high mountain tours, and alpine expeditions, as well as for anyone who gets cold quickly at night. With the innovative SYNMAT PLUS TECHNOLOGY™, the recycled, synthetic microfibre filling is combined with an additional layer of reflective foil. This maximizes thermal performance while keeping the mat light, quiet, and compact. All our backpacking mats feature Cradle Comfort™ for added comfort: the vertical outer air chambers are slightly raised for even better support on the mat..The recycled and bluesign® recognized ripstop polyester is ultra-light and three times stronger than conventional materials. Thanks to the two flat valves, the mat can be inflated effortlessly and deflated just as quickly – robust, reliable and intuitive to use. The Schnozzel pump bag included ensures fast, moisture-free inflation.
