It might not look like much at first, but Reigning Champ's Trail Cap is all about performance with a stealthy look that'll keep you under the radar. Take a close look at the photo above and you'll notice there is virtually no exposed stitching in sight with its smooth 3-layer waterproof and breathable fabric that is fully seam sealed, has four-way stretch for fit and comfort, and a moisture-wicking headband.
