This hat was designed as a hat that combines the look and attitude of a trucker hat but with performance in mind. Performance fabrications in the front panel means a lightweight trucker that you can train, race or use for everyday activity. There is a mesh polyester liner behind the front panels that will wick sweat while you sweat. The Technical Trucker hat has a performance wicking sweatband that will move moisture to keep you comfortable during any activity. This hat is a member favorite!
