Hello Mark, Thank you for your inquiry! The Body Glove 8oz. Junior 540 Lycra Short Sleeve Rash Guard is not a wet suit. It is meant to help a diver keep warmer while submerged in the water. If used by snorkelers and surfers while on the surface, they will chill due the breeze of wind. We recommend a neoprene 3mm Barrier Front Zip Wetsuit Vest by Body Glove. The Zipper Vest will assist in keeping your son warm while on the water surface. http://www.scuba.com/scuba-gear-43/052612/Body-Glove-3mm-Barrier-Front-Zip-Wetsuit-Vest.html
