Sun Bum Signature is one of our favorite products for long days at the beach. This stuff is trusted by athletes and outdoorsmen to fully protect against sun damage without constant reapplication. The only downside is that it takes some scrubbing to get it off at the end of the day. Sun Bum Signature is well worth the hype.
