More about Robens HeatCore 5.9R Regular

The core of the construction consists of triple foil insulation, which provides a highly efficient warmth-to-weight ratio. It reflects body heat back and minimizes heat loss to the ground, while keeping the weight surprisingly low. Despite its high level of insulation, the base layer weighs only around 420 grams, making it one of the most interesting options in the ultralight winter base layer segment. The 7 cm thick construction together with horizontal air channels provide stable support and good comfort even on uneven ground. Robens Peak Valve with one-way technology ensures fast and efficient inflation, especially in combination with the included pump bag. The design with many smaller air chambers improves both stability and pressure distribution, providing more consistent sleeping comfort across the entire surface. The 20D ripstop nylon material provides a good balance between durability and light weight, while the soft surface contributes to comfort and helps the sleeping bag stay in place. HeatCore 5.9R is thus a clear choice for those who want maximum insulation in an ultra-lightweight format - without compromising on comfort or function.
