What Is Sealtex Classic?
Sealtex is a high technology, PU coated fabric, on a flexible, resistant polyester, which consistently achieves top scores on hydrolysis and hydrostatic testing. These garments are guaranteed to keep the wearer dry in adverse conditions, with welded seams to ensure wind and rain are locked out. The durable, stretchy fabric can be easily wiped clean, allowing all Sealtex garments to look good and last for longer.
What Is Texpel Splash Water Repellent Finish?
