ADVANTAGES OF A WETSUIT
Warmth in the water.
Warmth from wind chill when wet and out of the water.
A slight positive buoyancy gives confidence and reduces the chance of exhaustion while swimming.
Protection from sunburn and jellyfish stings.
HOW A WETSUIT WORKS
A snug fitting wetsuit keeps a thin layer of water between your skin and the suit. Your natural body heat, insulated by the material (neoprene) of the suit, warms this thin layer of water.
The closer the fit of the suit to your own body shape the warmer the suit will be, so don't try to get two years growth out of your childs suit - it just won't work, being too big for the first year and quite possibly too small (hence uncomfortable) for the second.
