HDry is an advanced technology for waterproofing outdoor products through direct 3D lamination of a waterproof-breathable membrane. The HDry compound is made by a polyurethane ester-based waterproof-breathable membrane combined with thin polyester knit. Material saving and lightness are its greatest advantages. It is PTFE-free, and no perfluorinated compounds (PFCs, PFOs, PFOAs, etc.) are used in its production. It does not contain any restricted substance on the REACH–ECHA list and is OEKO-TEX certified.
