The time that the DWR treatment can last is what the garment is being used for.
If you use the garment several times per week for intense periods of activity, the DWR treatment will last a lot shorter than if a jacket is used only a few times per month.
In addition, the DWR applied at the factory to a new garment typically lasts longer than the reapplications of an old jacket. This is because the fastness is declined.
Try sprinkling some water on your jackets to test your jacket’s DWR treatment quality. If the water beads up, your DWR is in good shape. Otherwise, the factory did not do a good job.
If the water soaks i, it is time to restore your DWR treatment, or just buy a new jacket. Be sure to test your ski jacket all over, as soaking can occur from any breach.
