Robens LightCore UL 3.1R Sleeping Mat - Regular

Product Information

For hikers, backpackers, and campers who demand lightweight gear without sacrificing warmth, the Robens LightCore UL 3.1R is a sleeping mat built for serious trail use. With innovative materials and smart design, it delivers comfort, performance, and packability in one ultralight package. Weighing just 310 g, it’s easy to carry on long treks, bike packing trips, or minimalist camping.

Utilising a 15D 430T ripstop nylon with a TPU coating, the mat is both lightweight and highly durable, resistant to punctures, and soft against the skin. Its horizontal baffle design adapts to your body shape, providing firm support and stable comfort while minimizing heat loss.

The mat features a single layer of foil insulation, giving it an exceptional warmth-to-weight ratio. With an R-value of 3.1 (-4°C), it provides reliable insulation for 2–3 season use, keeping you warm on chilly nights without adding unnecessary bulk.

Inflation and deflation are effortless thanks to the Robens Peak Valve, which combines one-way technology with high airflow properties for fast, hassle-free setup. The included lightweight pump sack speeds up inflation, while the mat seals securely to retain air throughout the night.
