Highlights & Technologies:

AQUASEALZ MEMBRANE TECHNOLOGY:
The hydrophilic (water-loving) solid polyurethane barrier membrane is not porous and therefore has no microscopic holes like a microporous hydrophobic (water-repellent) membrane. The membrane has a solid structure that prevents water from passing through the membrane. It’s breathable by absorbing and releasing sweat through the diffusion of water vapour molecules. The chemical structure of the membrane consists of hydrophilic groups that attract water vapour molecules. Driven by greater heat and water vapour density, the water vapour molecules move from one hydrophilic group to the next.
