Introducing the Cloud Layering System - hiking & backpacking apparel that provides you with the functional performance you want, when and where you need it. The traditional layering system of a hardshell combined with a midlayer doesn't work. The hardshell lacks breathability because it also needs to be waterproof. If you try to use the hardshell for wind protection, it will lead to active perspiration. The midlayer offers no wind protection, which results in rapid evaporative heat loss.
We took apart your traditional 3-layer waterproof/breathable jacket and separated the windproof layer from the waterproof/breathable layer. This results in a shell system that provides the best of both worlds: active all-day performance and maximum waterproof/breathable protection. Layer up windshell performance with airshell sensibility and you've got all the lightweight, functional versatility you need without sacrifice. Men's Journal even said the Cloud Layering System is "layering done right".
