ThermicFibre 6

Thermicfibre 6, the successor of Hollowfibre 6, consists of spirally twisted polyester fibers with six channels.

The air retained in these channels provides excellent insulation. Due to their flexible structure and specific layering, the fibers achieve what is called LOFT. This means that after unpacking, they regain their original volume and fill the compartments of the sleeping bag.

Maximum performance and durability are achieved by applying a thin layer of silicone to the fibers' surface, fixing their positions and reducing friction between them.

Hollow fibers provide excellent insulation even in high humidity, are non-absorbent, dry quickly, are non-allergenic, and easy to maintain—machine washable and dryable.
