The Atlantis 4 is an all-weather-touringsuit made from hydrophobic suede cowhide. This type of leather is not only waterproof but also, because of its low absorption rate, very fast drying. Its open pore structure offers a natural and comfortable climate zone and a very high breathability. This concept brings, also without a membrane, a maximum of rain protection. To further reinforce the latter all the seams are taped inside, with the resulting effect that no water can ever enter. Also, the outside zippers have been treated with a rubber coating to be water resistant as well.
