Review: Necessity for water-cold people - I’m the only dad a shorty wetsuit at the indoor or outdoor pool on a 90° day where we live, but I’m no longer feeling hypothermic everytime I get in the water for my kid. I wear this under basic black swim shorts and a 3/4 length long sleeve oneill swimming shirt. This way I feel less awkward while also being much less cold. Quality is great. Zipper is easy and strong, the long tail of it makes it easy to do yourself and also makes you feel sort of ninja-like. Over a year later and it’s holding up. 3 trips to Great Wolf, and maybe 50+ swim days. Only just starting to see the logo start to crack.
Review: Warm and fits like a glove - I like that it has a windproof material on the chest and back as I use this to kitesurf with. Quality is great and I love that I can fold the zipper pull over the velcro strap to make sure the back doesn't unzip during a session. I did go a size larger as other reviews have pointed out and mine fits perfect. So you know, a wetsuit should be like a second skin. snug but not tight. If you can't breath or it is restricting movement you went too small if it is baggy you went to big as this won't keep you warm. Also note these stretch out a bit over time so if at first it is a little tight give it time to break in. Otherwise return before using it and get the size you need.
