Certain TUSX products come factory treated with a Durable Water Repellent (DWR) finish. DWR is a polymer-based, chemical compound treatment applied to the face fabric during manufacture. It works by lowering the surface tension of the fabric, this will in turn cause water droplets to bead up and roll off.  In time, dirt and body oils, abrasion, and multiple launderings can diminish the effects of DWR. This will result in the fabric absorbing moisture more readily or ‘wetting out’. At this time, we recommend using Nikwax SoftShell Proof Wash In to restore and revitalise the garments DWR. Reproofing of DWR is dependent on use, as an approximate guide, annual treatment at the beginning of the hunting season will suffice the typical active user.
