O'Neill Men's Reactor-2 2mm Back Zip Short Sleeve Spring Wetsuit, Lightweight Warmth and Flexibility for All Water Activities

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.

This is a great wetsuit and remarkably fit me perfectly.

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.

I've attached three photos to show the quality of the seals around the openings of the O'Neill Men's Reactor-2 2mm Back Zip Short Sleeve Spring Wetsuit: (1) The 1st photo shows the long single-piece rubber neck. This single-piece design avoids seams that may leak. The smooth rubber layer of the fabric forms a seal around most of my neck. (2) The 2nd photo shows a leg opening. Again the smooth rubber layer of the fabric forms a seal against my leg. My only criticism here is that the diameter of the opening is small and feels tight. (3) The 3rd photo shows the back zipper. Unfortunately, when zipped, the rough fabric layers of the neoprene are making contact in an attempt to form a seal. I would have preferred that the smooth rubber layers are used to form a seal. The photo also shows a loose thread that may jam the zipper. The design and aesthetics of the O'Neill shorty are top notch. I do notice some shortcomings in the zipper seals and tightness in the leg openings. Overall, I believe that it deserves 4 of 5 stars.

I always go with O'Neil for wetsuits. They are extremely well made and designed to look good. Got it in 1 week and I am psyched about it. First time I went bodyboarding I got in the water and no water came in. It slowly lowered my body temperature and reduced the cold water shock that leaves you gasping for air when you first enter the water. I live in the Caribbean so water is actually not that cold, making this the best option for good protection and warmth while ripping those waves.

I was astounded to see O’Neill wetsuits at such a bargain and I had to get 3! The fit is perfect, the value for money incredible. I am so happy with them !

Worried that it would be a one size fits all type but it had the extra room in the front that the size promised. All aspects good

I like it

Servicio excelente

Very happy with my purchase. Keeps me dry and warm when weather is cool while on jetski

6’1” 250lbs and it fit perfectly

My first Oneill reactor lasted me over twenty years and it was time for a new one. This new one is made of much softer stretchier neoprene. Ordered same size as the first one and fit the same.

I have fat heavy lifter body. 5'11 285lb . Wide shoulders but belly. Usually I'm wearing 2xl but I read comments and took one size up. 3XL fits me like a glove. Feel warm. Exited to try it on a water.
