Mountain Hardwear Dry.Q Elite
Dry.Q Elite - For users who are continually pushing their own Human Potential in Alpine environments.
Traditional waterproof-breathable systems work by moving moisture out through the shell fabric. the trouble is, you have to get hot before they start working. That means waiting until you're clammy and damp before the breathability kicks in.
Dry.Q Elite doesn't make you wait. It's air-permeable membrane allows air - not just moisture - to pass outward through the fabric. That always-on air flow won't wait for you to get hot first. With Dry.Q, breathability and comfort starts the moment you put on your jacket.
