ACD Membrane
This is a registered trademark of a unique membrane from a renowned Japanese manufacturer. Pinguin has over 10 years of experience with its parameters, functionality, and durability, confirming the correctness of our decision to continue using this now traditional and proven product for Pinguin waterproof clothing under new business conditions and the new trademark **A.C.D. (All Climate Dry)** membrane.
**A material that breathes.** The **A.C.D. membrane** is non-porous, which fundamentally distinguishes it from classic microporous membranes. Nevertheless, its ability to transmit (breathe out) evaporated sweat reaches top levels. This is due to the membrane's microstructure made from special polyurethane (PU), whose molecular structure and the forces between PU molecules and water are optimal for this function. During physical exertion, the body heats up, sweats, and the concentration of vapor under the clothing increases. When a water vapor molecule approaches the **A.C.D. membrane**, it is absorbed between the PU molecules, temporarily becoming part of it (i.e., the membrane is hydrophilic). Due to the higher temperature and concentration of water vapor inside the clothing, evaporated sweat is smoothly pushed through the membrane. This is as natural a process as water flowing from a higher to a lower place.
**Waterproof and windproof.** The micropores of classic membranes expand over time in stressed areas and let water through. The non-porous **A.C.D. membrane** retains sufficient resistance to water pressure even after years of use. 100% wind resistance is essential for maintaining the microclimate and thermal comfort of the user.
**Durability and care.** A typical problem of classic membranes is the gradual clogging of pores, leading to deteriorating breathability. Salts and fats contained in sweat, dirt, and detergents can settle in the pores and block them. The **A.C.D. membrane** does not suffer from this issue. It can be machine washed with regular detergents, gently dried in a dryer, and ironed. The only recommendation is to avoid using fabric softeners. After washing, the clothing should not be twisted or spun; just let it drip dry.
