This can come in handy for any open water swim "panic" as the neoprene wetsuit will give kids an extra lift and make it easier to float while they bring their heart rate down and their focus back to swimming. 2. Free Speed The buoyancy of the diving suit allows the wearer to swim faster than without the suit. A swimmer can expect to save anywhere from a few seconds to tens of seconds per 100. Usually, the longer the distance the more the savings are noticeable. 3. Keep Warmth The thickness wetsuit can provide warmth for the swimmer in the cold water. If children are sensitive to the cold, this can be great at making them more comfortable in the water. 4. Protect Children The flat-lock stitching process used in our thermal wetsuits takes into account flexibility, excellent strength and durability. It can prevent kids' bodies from being damaged by reefs and jellyfish stings, and escort boys' and girls' safety in the water.
