Centrex shorts are session savers. They allow you to surf as long as you want, day after day, without developing rashes from your boardshorts.
Centrex shorts are more spandex than neoprene. They’re ultra thin, light, breathe, stay cool, and fit comfortably under boardshorts.
Xcel Centrex shorts are also ideal for long distance paddling, swimming, and any other water sport that you want little drag, and more protection than a speedo provides.
You can find them online, or at your local core surf shop. Mitch’s in La Jolla carries them if you live in the San Diego area.
Highly recommend packing Centrex shorts if you’re going on a surf trip to a warm water location.
