Robens HeatCore 3.8R Large

is designed for those who prioritize comfort and light weight, but want more space than a standard pad offers. With a wider and longer construction, you get more freedom of movement during the night - something that makes a big difference on longer trips or for larger users.

More about Robens HeatCore 3.8R Large

The core of the construction is based on double foil insulation in combination with MicroThermo Highloft, which provides a very efficient warmth-to-weight ratio. The insulation reflects body heat back and reduces heat loss to the ground, making the underlay well suited for 3-season use. With an R-value of 3.8, it performs confidently from spring to fall and can withstand cooler ground conditions. The 7 cm thick construction, together with many smaller air chambers, provides both high comfort and stability - without the ground feeling wobbly or unstable. The Robens Peak Valve ensures fast and efficient inflation and deflation, and the included pump bag makes it easy to fill the mattress without adding moisture. The durable ripstop nylon material provides a good balance between light weight and durability. HeatCore 3.8R Large is thus a clear choice for those who want extra comfort and space - without stepping up to heavier and more cumbersome alternatives.
