Fashion meets function- I'm made with sophisticated stretch woven fabric with tight layered weaves and a durable water repellent treatment to guard against wind, rain and snow in all but the most severe weather conditions. In other words, I keep weather out like a hard shell but breathe like fleece. Keeping you comfortable during aerobic activities, regulating your temperature much more effectively and remaining comfortable during rigorous activity. I'm made in a 4 way stretch fabric making me extremely comfortable. My chic, classic design dresses up any outfit. A timeless investment piece you need in your wardrobe.
