Learn more about the membrane
A membrane for a cycling jacket is a layer of waterproof and breathable material built into the jacket to provide protection from the elements while allowing perspiration to escape.
This membrane acts as a barrier against water while allowing water vapor generated by your body during physical exertion to escape, keeping you dry and comfortable inside the jacket.
The membranes used in cycling jackets are usually high-performance synthetic materials, such as Gore-Tex, eVent, Dermizax, Pertex Shield, etc.
These membranes are designed to be waterproof yet breathable, meaning they keep water out while allowing sweat to evaporate, preventing heat and moisture buildup inside of the jacket.
Cycling jackets with membrane are very popular among cyclists because they offer effective protection against rain, wind and other bad weather while allowing effective sweat wicking, making them comfortable to wear even during activity
