What is the waterproofing of a jacket?
Designed with a coating on the outer fabric to make it waterproof The resistance of a fabric is measured by the height of a water column in mm (JIS standard). The higher the water pressure, the more waterproof the fabric. A component with a waterproofing resistance of 5,000 mm resists the pressure of a 5,000 mm column of water (Schmerber). Validated in a shower test under 60L/sqm/hour of water which is roughly equivalent to a 2 hour rain shower Test carried out before washing.
What do you mean by taped seams or waterproof strips?
These sealed (or taped) seams are closed with waterproof heat-bonded strips. Stuck behind the seams, they are essential for making the garment waterproof, given that water can get inside by capillary action (water absorbed by the yarn and/or through the stitching holes)
Fleece material: Insulation provided by air
The fleece component is designed to trap air in the space formed by its texture; this air acts as a natural insulator, keeping the body warm. It is the brushing of the knit fabric that traps the air.
Washing:
1/ Machine wash (30°C): fasten rip-tabs and use mild detergent. Wash jackets and trousers inside out. Loosen the straps and elasticated parts. 2/ Do not fold the garment too much in the machine: may wear out more quickly. 3/ Do not mix clothing types and colours. 4/ Do not use bleach. 5/ Choose a full rinse and gentle spin cycle.
