Highlander Nap-Pak Arctic R11 Insulated Sleeping Mat R-Value 11
Experience true four-season comfort and unbeatable value with the NAP PAK ARCTIC R11 — a ultralight, winter-ready sleeping mat engineered for warmth, comfort and packability.
• Exceptional Warmth – R-Value 11:
Tested to ASTM F3340 standards, the NAP-PAK ARCTIC delivers an R-value of 11, giving you genuine 4-season insulation and far superior cold-ground protection than most mats on the market.
• Lightweight & Packable:
Weighing in at just 900 g, and compressing down to roughly 28 × 14 cm, this mat is light enough for backpacking yet warm enough for winter camping.
• Plush Comfort – 10 cm Thickness:
The thick 10 cm baffle structure provides cushioning and insulation, helping you sleep soundly even on hard or uneven ground.
• Advanced Insulation – Triple-Layer Foil:
Inside the mat, a 3-layer aluminium foil barrier reflects your body heat back at you and blocks cold from the ground — delivering stable warmth and minimising cold spots on chilly nights.
• Supportive & Stable Surface:
Interlinked air-cell baffles ensure even pressure distribution, offering a stable and comfortable sleeping platform without lumps or sagging.
• Durable & Pack-Ready:
Built from 20D ripstop nylon and fitted with a dual-layer TPU valve (for precise inflation/deflation), the mat is both light and rugged — perfect for repeated outdoor adventures.
