Highlander Nap-Pak Arctic R11 Mummy Lite Inflatable Sleeping Mat

The Highlander Nap-Pak Arctic R11 Mummy Lite is a space-saving, lightweight evolution of the Arctic R11, delivering an exceptional ASTM F3340-tested R-value of 11 at just 600g. A tapered mummy shape trims weight and bulk while keeping the critical warmth zones.

A 10cm air-cell construction with a 3-layer aluminium foil system separates you from cold ground, while a dual-layer TPU valve gives precise inflation and firmness control. Built on a 20D nylon ripstop shell and packing to 24 x 10cm, it is backed by Highlander's lifetime (282-year) guarantee.
