Product Information

Full details

The Highlander Nap-Pak Arctic is designed for serious mountaineers, winter backpackers, and four-season expedition campers who require reliable thermal protection against sub-zero terrain. Its core advantage is the industry-leading R-value of 11, providing unparalleled insulation from frozen ground, though its 900g weight may be slightly heavier than basic summer-only sleeping pads for ultralight hikers.

Extended Product Information

FAQs

What is the R-value of this mat?

The Highlander Nap-Pak Arctic has an R-value of 11, making it suitable for extreme four-season conditions.

Does it come with a patch kit?

While the mat is made of durable 20D ripstop nylon, it is standard practice to carry a universal TPU repair patch kit for field repairs.

Can I use this in summer?

You can use it in summer, but its insulation level is designed specifically for cold environments and may cause overheating in warm weather.

How do I inflate it efficiently?

We recommend using an air pump sack to prevent condensation build-up inside the mat, which can occur when inflating by mouth.

What are the dimensions when packed?

The mat is designed to pack down compactly, though exact dimensions vary based on how tightly it is rolled into its provided stuff sack.

Troubleshooting

Difficulty inflating to max firmness

Ensure the dual-layer valve is fully seated and that you are using a consistent inflation rhythm; consider using a dedicated pump bag for efficiency.

Slow air loss over time

Check the valve seal for debris or frost buildup; clean with a soft cloth and ensure it is snapped shut securely.

Surface feels slippery

Ensure your sleeping bag has anti-slip strips or use a small amount of textured fabric between your bag and the mat if necessary.

Pros and Cons

Pros

Exceptional R-value of 11 for extreme cold protection
Thick 10 cm loft provides mattress-like comfort
Durable 20D ripstop nylon construction
Dual-layer valve allows for precise firmness control
Relatively low weight given the extreme insulation level

Cons

Slightly heavier than minimalist summer sleeping mats
Inflation takes time due to the high volume of the 10 cm baffles
Best suited for extreme conditions rather than casual warm-weather camping

Setup, Compatibility & Care

To set up the mat, clear the area of sharp sticks or debris before laying it down. Open the primary valve to inflate; due to the large air capacity, you may wish to use a pump sack to avoid introducing moisture from your breath into the insulation layers. For storage, keep the mat loosely rolled in a dry, cool place away from direct sunlight to preserve the integrity of the TPU coating and the internal aluminum film. If the mat gets wet during an expedition, wipe it down and allow it to dry completely before long-term storage to prevent mold or material degradation.
