Wetsuit: A wetsuit is a special foam rubber suit that we wear to help keep us warm underwater and to protect us from getting cut or scratched. A wetsuit provides insulation as well as protection, and can keep us comfortable in water as cool as 50ºF. Wetsuits get their name because even though they keep you warm, you get wet – they trap a small amount of water between the suit and your skin that your body quickly heats. Required Features Proper Fit: Wetsuits work best when they fit very snug so the warm water trapped between our skin and the wetsuit does not get flushed out by the outside, colder water coming into the suit. For that reason we look for wetsuits that are form-fitting, like a second skin. Proper Thickness: In warmer water we wear a thinner suit. In colder water we wear a thicker suit. (In REALLY COLD water we wear a special drysuit, which keeps us totally dry!) AQUA LUNG® AquaFlex Wetsuit Jumpsuit The wetsuit Mr. Brown wears is a form-fitting AQUA LUNG® AquaFlex wetsuit jumpsuit. The jumpsuit style of wetsuit is one piece with a single zipper on the back, like a surfing wetsuit. The high quality AquaFlex jumpsuit is one of the warmest and most durable available today. Not only is it warm but because of the soft and stretchy AquaFlex material it is very comfortable, too!
