Nap Pak Arctic R11 Inflating Sleeping Mat – All Year 4 Season Winter Camping Mat – R Value 11 Insulated Alpine Sleeping Pad – 10cm Thick, Lightweight 900g, Compact – Cold Weather Backpacking Use.

• Will it keep me warm on snow or in winter conditions?

  Based on its ASTM-tested R-Value and three-layer aluminium film insulation, the mat is designed to reduce heat loss from cold ground, including snow and winter conditions. As with all mats, perceived warmth depends on the complete sleep system.

• What does “R-Value 11” mean, and why should I care?

  The R-Value measures how well a mat resists heat loss to the ground. An R-Value of 11 is exceptionally high and is measured using the ASTM F3340 industry standard. This places the mat well above typical winter mats, which often sit around R6–R8.

• Can this mat really compete with more expensive alternatives?

  Yes. Independent ASTM F3340 testing confirms an R-Value of 11, which compares very favourably with many premium mats at higher price points. This mat is designed to deliver outstanding insulation performance and value.

• How comfortable is it compared to other mats?

  At 10 cm thickness with interlinked air-cell baffles, it provides a supportive, cushioned sleeping surface that keeps you well off the ground and distributes weight evenly, offering noticeably more comfort than thinner or basic budget mats.

• How durable is the mat? Will it puncture easily?

  The 20D ripstop nylon balances low weight with durability. Normal use on grass, soil, or inside a tent is well within design intent. As with all mats, sharp rocks, spiky vegetation or rough ground should be avoided/protected with a groundsheet.

• EXTREME COLD PROTECTION – R VALUE 11: Engineered for true winter conditions. With an ASTM-tested R value of 11, the Arctic R11 delivers serious insulation for sub-zero camping and snow conditions where standard mats fail.
• 10CM DEEP BAFFLE COMFORT: Thick 10cm construction with advanced internal baffle structure eliminates cold spots and ground pressure. Sleep warmer and more comfortably, even on frozen ground.
• 3-LAYER THERMAL REFLECTIVE INSULATION: Integrated aluminium film layers reflect body heat back to you, dramatically improving thermal retention compared to standard self inflating mats.
• LIGHTWEIGHT FOR ITS CLASS – ONLY 900g: High-performance winter insulation without excessive bulk. Weighing just 900g and packing down to 28 × 14cm, it’s built for serious backpackers and mountaineers.
• DURABLE 380T 20D NYLON + DUAL TPU VALVE: Hard-wearing outer shell resists abrasion in harsh terrain. Dual-layer TPU valve enables fast inflation, deflation and micro-adjustment.
