Our popular Mens/Unisex sized Wind Jacket & Vest is very light weight and easily fits in your jersey back pocket, fanny pack, or purse. See our size chart image above- easy to determine size by your chest measurement. Women also wear our Unisex Jacket/Vest. Vented back for added breathability, the sleeves also zip off quickly to make into a vest. The back pocket has a zipper, for snacks, cell phone, etc. Our customers tell us this is their “go-to” jacket & vest all year long for cycling, running, skiing, fishing, walking, hiking, birding, or any activity! When you are exercising outdoors and its chilly, rainy, foggy, windy or snowy and a water proof rain coat is too heavy, this is the perfect light shell and easy to stash or tie around waste after you warm up. This jacket is wind proof and water resistant enough that it makes activities in cool or inclement weather more comfortable. We are a small family business (husband & wife team) so if you call or email us, you will talk to either Pat or Kathy the owners. Kathy is the artist that creates Free Spirit Wear's original artwork for all 50 states as well as other bright beautiful designs.

Customers call our jerseys and jackets ""conversation starters” and many claim to have "more fun" when they wear our products, due to the positive attention the artwork creates.
