Reinforced shin guard Held-Tex-Z-liner All climate membranes have the same basic function: they protect the body from moisture from the outside, keep out the wind & transport body perspiration from the inside to the outside by exploiting a temperature gradient. This gives the clothing excellent weather protection & comfort at the same time. All membranes are made from polyurethane or polyester & reliably transport water vapour molecules to the outside along molecular chains by chemical-physical means. The pore-free homogeneous structure does not allow the wind to penetrate & thus prevents the body from cooling down. For a waterproof construction, each individual seam is welded with a special heat-sealing tape so that no water can penetrate from the outside through the seams. Depending on the product br&, the membranes are made from different basic materials & are usually incorporated as a loose film ("liner") on the inside of jackets & trousers. Special materials & special processing guidelines make the membranes extremely hard-wearing, stretchy & extremely tear-resistant.
