More about the Robens HeatCore 3.8R Regular
The core of the design consists of double foil insulation combined with MicroThermo Highloft, which provides a highly efficient warmth-to-weight ratio. This solution reflects body heat back and minimizes heat loss to the ground—a clear advantage on cold nights.
With a thickness of 7 cm, the sleeping pad offers good comfort even on uneven surfaces. The numerous small air chambers provide stable support across the entire surface and reduce the risk of “sagging,” which is especially important on longer trips.
Its light weight (approx. 380–385 g) and compact pack size make the HeatCore 3.8R a very attractive option for those who travel long distances with their gear. At the same time, Robens’ Peak Valve ensures quick and efficient inflation using the included pump bag.
The ripstop nylon material is both durable and comfortable, with a surface that helps keep your sleeping bag in place throughout the night. The combination of robust construction and low weight makes this a sleeping pad that works just as well for hiking as it does for more general outdoor activities.
The HeatCore 3.8R is therefore a clear choice for those who want a lightweight, stable, and comfortable sleeping pad with reliable insulation—without having to resort to heavier winter sleeping pads.
