When it is all about demanding use in snow, wind and rain, waterproof hardshell jackets are indispensable for men. Shell jackets, as the name implies, consist of different layers. Membranes such as GORE-TEX® or DYNASHELL™ are very robust and durable for rain, wind and abrasion, plus they are also breathable. In 3-layer jackets, the outer layer protects from physical abrasion. The mid-layer ensures moisture from the exterior is stopped from entry. For nice comfort you have the inner layer.
