This wetsuit was bought for my 7 year old son. He is small for his age and weighs 42 lbs. I bought a size 4 which was perfect for him. I was going to buy a size 3 because of his size; yet went with the 4 because I thought he could grow into it for next summer as well. Glad I went with the 4 because the size 3 I feel would have been to small. Item is very thick and keeps him warm learning to surf and in the morning for swim team practice.
We use this product so that our 7 yr. old son can swim in the water without turning blue. This wetsuit worked miracles for him. He no longer felt the coldness of the water and moves in his suit freely in the water. He now enjoys swimming at the school swim program. He looks forward to his class every week with no complaints. He also loves how he looks and feels in it. What a Godsend!!!!
