Extreme Insulation for Cold Conditions

The Highlander Nap-Pak Arctic R11 Sleeping Mat is built for serious cold-weather performance, delivering exceptional insulation with a certified R-value of 11-ideal for winter camping, alpine use, and sub-zero conditions.

Designed with a 10cm thick baffle construction, it provides both comfort and ground insulation, helping you retain warmth and recover properly after long days outdoors. Inside, three layers of aluminium film insulation work to reflect body heat, maximising thermal efficiency in extreme environments.

Despite its high level of insulation, the mat remains compact and packable, making it a practical choice for backpacking, mountaineering, and cold-weather expeditions.

The dual-layer TPU valve system allows for quick inflation and precise adjustment, so you can fine-tune firmness to suit your comfort. For even faster setup, pair it with the Highlander Wee Banshee Mini Air Pump.
