Water repellent property of component (not to be confused with waterproofing)
The water-repellent property of a fabric is its capacity to make water run off its surface without absorbing it.
This prevents the fabric from soaking up water and keeps it lightweight and breathable. The fabric is made water-repellent by treating its outer surface, however this property may deteriorate with use.
The water-repellent property can be reactivated by putting the jacket in the tumble dryer for 10 minutes on low heat.
