Technical garments have a membrane and DWR coating that ensures the garment performs at its peak and is not absorbing water.
(The DWR performance can be reduced by dirt, sweat, grease, washing powder and general use. Dirt and debris accumulates on the surface and in the microscopic pores of the fabric, it can then begin to lose breathability and water repellency.)
Therefore keeping garment clean ensures that it performs as intended.
Proper cleaning revitalises the fabric without damaging any active DWR treatment. Using a domestic laundry detergent is not suitable when it comes to the care of technical outwear as it damages the DWR on the garment, as they contain many compounds which are not advantageous to the performance, bleaches, colour brighteners, enzymes and perfumes.
When a garment is new and only dirty, a clean may be all that is required. However an older garment may require a bit more care as it loses its water repellency over a time, this can be easily restored with addition of a proofer.
Shake bottle and pour 75ml into detergent compartment. (If garment needs proofing use a Storm Proofer to suit). Wash following garment manufacturer’s care guidelines.
