Highlander NAP-PAK Arctic R11 Mummy Lite inflatable sleeping mat

The Nap Pak Arctic R11 Mummy Lite is a lighter, space-saving evolution of the inflatable Arctic R11 sleeping mat. Thanks to its weight-reducing 'mummy' shape, excess material has been removed, bringing the mat’s weight down to just 600 grams. This makes it an excellent choice for backpackers, bikepackers, and anyone seeking reliable insulation without the burden of unnecessary extra weight. Once packed, the mat is extremely compact—measuring 24 x 10 cm—making it a top-tier option in its class.
