Performance flannel. It’s got medium weight for durability, it’s stretchy and soft for all-day comfort and mobility, and our proprietary fabric wicks moisture and dries fast so you can take it anywhere. Plus, it’s got loads of functional features like a built-in lens cloth, sunglasses holder, and a hidden zippered pocket. Originally 95. My husband lost weight and it’s now too big. Minimally worn-like new condition!
