WASHING YOUR JACKET TO KEEP IT LIKE NEW FOR YEARS TO COME
Rainwear fabrics are highly specialized and come with a DWR treatment on their face. This treatment penetrates the fibres of the fabric, which allows water to bead up and roll off the fabric’s surface rather than being absorbed.
This ensures a high level of water resistance – an extra layer of protection in addition to the waterproof membrane below the surface fabric.
However, with heavy use and time the DWR will wash or wear out. Dirt, sweat and sunscreen are just a few of the things that can also decrease the effectiveness of the DWR and cause your garment to “wet out.” This is when the DWR on the surface of your waterproof apparel has worn off, allowing water to saturate the garment above the membrane and then making you feel clammy, damp or wet. Fortunately, proper care and washing can help restore both the DWR treatment and then increase the garment’s performance and longevity.
If you’re using waterproof jackets for hiking or high output activities like ski touring or running we recommend you wash your jacket more frequently.
