This R11 mat has quickly built a reputation as one of the best-value four-season sleeping mats available in the UK. With an ASTM-tested R-value of 11, it delivers genuine winter-grade insulation at a price far below the usual premium alternatives.

Key Features

1. R11 insulation for true winter and snow conditions
2. 10cm thickness with air-cell baffles for comfort
3. Lightweight 900g design suitable for backpacking
4. Durable 20D ripstop nylon shell
5. Three-layer aluminium reflective insulation
6. Dual TPU valve for fast inflation and deflation

Real-World Performance

Users consistently report excellent warmth retention, even in sub-zero temperatures. The reflective layers noticeably radiate heat back toward the body, reducing heat loss to frozen or wet ground. Several reviewers have used it in -8°C conditions, on snow, and during demanding trips such as Hardangervidda in Norway.

Comfort is another strong point. The 10cm depth and baffle structure help distribute weight evenly, preventing pressure points and keeping elbows and hips off the ground. Taller users also appreciate the 189cm length and 63cm width.

Packability and Weight

At around 900g and packing to roughly 28 × 14 cm, the mat strikes a balance between warmth and portability. It is not quite the lightest mat on the market, but for its insulation level, it is exceptionally competitive.

Durability and Tips

The 20D ripstop nylon shell offers good durability for normal camping conditions. As with all lightweight inflatable mats, care on rough ground is recommended.

A few users note that the valve releases air quickly when opened, so snapping it shut promptly helps maintain firmness. Deflation can take a little patience, but rolling tightly resolves it.

Who This Mat Is For

Ideal for campers, backpackers and winter hikers who want one mat capable of handling year-round UK conditions without paying premium-brand prices.
