The Robens Polarshield 60 Double offers unmatched comfort and warmth for campers who demand reliable performance in tough conditions. This self-inflating mat features an innovative 3D construction with vertical sides that maximise sleeping space while preventing cold spots through cleverly positioned vertical cutouts. These cutouts create dual rows of rounded air pockets, adding an extra 2 cm of cushioning without compromising on weight or packability. Crafted from delamination-proof TPU bonded to ripstop nylon, the mat resists punctures and maintains structural integrity even after years of outdoor use. The Robens Peak Valve features one-way technology for fast inflation and deflation, while the static side fabric preserves the 3D shape during setup and prevents unwanted bulging.
