MAKING OUR GARMENTS WATERPROOF
Waterproofing our fabric
STEP 1
STEP 2
Preventing water penetration by one of two methods; applying a durable water repellent membrane or a double coating of polyurethane (PU). Both methods ensure the garment is waterproof and breathable.
We apply our fabric finish, Durable Water Repellent (DWR), which ensures the water rolls up and beads off the fabric, avoiding water build up.
WATERPROOF MEMBRANE
DOUBLE PU COATING
WATER REPELLENT FINISH
Our 300D fabrics use a double coating of polyurethane (PU) for guaranteed waterproofness. Our application process creates microscopic holes which let perspiration out but doesn’t allow water droplets in.
Portwest Extreme TM uses a waterproof and breathable membrane, a durable water repellent (DWR) finish on face fabric and a breathable backing fabric. These combined technologies allow moisture to escape, while preventing water penetration.
Texpel™ SOS, Splash, Oil and Stain is a premium fabric finish which repels oil and liquids, causing them to bead up and roll off the fabric surface. Texpel™ Splash is an extremely water resistant fabric finish.
