Comments about Henderson Thermoprene 3 mm Child's Back Zipper Shorty, Black/Blue:

My son is 8, 50 lb, and 47 inches tall. I got him a size 4 and it fits him well. I even bought the next size up, so when he grows a bit, he can pass down the suit to his little sister. I would rather have it more fitting than baggy, which defeats the purpose of a wetsuit. If your not sure, I would go by weight, as the suit stretches beyond the height parameter. The more flexible thermoprene is definitey worth it vs. neoprene. I bought these for swimming in pools and waterparks because my children are skinny and often cold. Both of my kids say that they're warm and my daughters lips weren't blue anymore. It didn't restrict their movement at all, and infact helps their swimming because the suit is a bit boyant. I was worried it would get stuck on waterslides, but that wasn't an issue. The only downside is that the first wear, my son put the neck strap too tight and it chafed the back of his neck. It doesn't seem to be an issue with applying it looser and now that the suit has stretched a bit with additioal wears. I am glad to support a company in the USA that makes these quality suits.
