Wetsuits kids
Children cannot do without a wetsuit during the triathlon. They benefit from the extra buoyancy. But it also protects them from the cold water. A wetsuit should be tight, otherwise water will keep getting into the suit and the insulating effect will be lost (the layer of water between your child and the suit becomes warm and must stay in place to stay warm). A well-fitting wetsuit is just not uncomfortable when your child is standing on the shore. The suit must be comfortable to wear/swim in the water.
