We have designed the perfect synthetic boxer-brief. Our new Ultra-light synthetic boxers are designed to work in tandem with all of the RailRiders pants and shorts. Made with 84% polyester and 16% Lycra spandex for great stretch, these new under shorts move moisture with the best of them. They have a soft face against the skin and a smooth outer face that lets them slide freely under all our synthetic pants. Not too short, not too long, take them for a test drive, you will be pleased at the way they handle the trails!
