Robens HeatCore 5.9R Regular Sleeping Mat

Premium Four-Season Warmth for Cold Weather Adventures

The Robens HeatCore 5.9R Regular Sleeping Mat is designed for adventurers who refuse to compromise on warmth, comfort, or packability. Featuring advanced triple foil insulation and an impressive R-value of 5.9, this high-performance sleeping mat delivers exceptional protection from cold ground temperatures, making it ideal for winter camping, mountaineering, and year-round outdoor use.

Built to provide an outstanding warmth-to-weight ratio, the HeatCore uses multiple reflective foil layers to maximise heat retention while keeping weight and pack size to a minimum. Whether you're camping in sub-zero temperatures or tackling high-altitude adventures, the HeatCore provides dependable insulation and all-night comfort.

The horizontal baffle design allows the mat to conform naturally to your body shape, creating a stable sleeping platform with excellent support. Combined with Robens' soft-touch fabric technology, the result is a sleeping mat that feels comfortable against the skin while remaining durable enough for demanding outdoor use.

Inflation is quick and efficient thanks to the Robens Peak Valve, which features one-way technology and high airflow performance for effortless setup and rapid deflation when it's time to move on.

For adventurers seeking lightweight winter-ready performance, the HeatCore 5.9R is an exceptional choice.
