Advantages

Graphene technology integrated into the 100% recycled polyester insulation provides superior thermal efficiency and durability. The horizontal baffle construction ensures stable support and prevents cold spots.

The 20D recycled polyester fabrics with internal TPU coating are lightweight yet robust, and the fluorocarbon-free DWR treatment adds moisture resistance.
