The baby wetsuit is made from Neoprene, which is the same kind of material that adult surf wetsuits are made from. It has Velcro fastening at the front and on the shoulders, you can undo the whole of the baby wetsuit so it lays out flat, simply lay your baby on and wrap it around them and stick the Velcro together. The suit then fits them snugly but it only covers their torso, so that their legs and feet are free to move around. As the straps are fastened by Velcro, they are adjustable, therefore you can loosen the straps as your child gets bigger. This baby wetsuit can protects against UV so that when you're on holiday it protects them from the suns rays, of course you still need to put suntan lotion on anywhere that is exposed to the sun.
