Innovato 5 We got this for our 6 yr old to start taking swim lessons in the autumn. It fits him well and gave him an extra boost of confidence with the buoyancy it provides. He also isn't turning blue and shivering 20 minutes into lesson now :) only thing to be careful with is to not lose the extra Velcro covering piece. If you don't use it, the Velcro can attach to other parts of the wetsuit and damage it a little.
