A key to the jacket is the rubber strip, which is the rubber strip that is pressed on the seam to prevent water leakage. The genuine product has undergone strict waterproof tests when it leaves the factory, and the rubber strip generally does not leak. However, the jackets we wear, as mentioned earlier, are generally fake goods, and there is no strict inspection procedure, so there are cases of water leakage, but generally not many. This is a problem of craftsmanship. Good rubber strips are all air permeable, but non-breathable rubber strips have little effect on overall air permeability.
The lining of the jacket is also made of breathable material, generally coolmax, mainly to enhance the perspiration and warmth retention. The lightweight jacket is made of mesh fiber, which does not stick to the body. There are also those that do not need lining, that is, the so-called three-layer glue and two and a half layers of glue. The three-layer glue is directly pressed with a layer of breathable material on the inside of the waterproof and breathable membrane to protect the breathable membrane from abrasion.
There are also some accessories, including zippers, bayonet, Velcro and so on. The zippers of jackets generally use YKK zippers. Jackets with fake YKK zippers are definitely problematic, so don’t buy them. YKK’s zippers can be bought in China, so the accessories are no longer a very important issue.
