O'NEILL Men's Reactor-2 1.5mm Long Sleeve Pullover Wetsuit Top, Lightweight Warmth with Good Flexibility

If you are muscular you must compensate and buy a larger size. I wear medium tshirts that are snug but fit and found the extra large fits snuggly. I couldn’t even venture to get into the medium. Overall the product looks and feels as advertised. Quality product.

I’ve purchased several of these over the years for water skiing. O’Neil is a good brand. I actually purchased a “used” or returned one because I know that people buy their normal size and wet suit tops are supposed to fit tight. That’s how they work. I figured someone tried this one on and sent it back because it was a large and too tight. It looks brand new and I saved $15. It fits as it’s supposed to but if you are not accustomed to wearing these, buy a size larger than you normally would. In my local water ski shop similar tops go for $150

Comfortable, fits good, for cold Hawaii mornings.👍🏾

Perfect fit, really great for mid 70s water. Very stretchy and easy to put on and take off.

My husband is 6’ and tried both the large and XL and both were not long enough to cover his lower torso. It stoops right about at his belly button. But overall great quality.

Fits like a glove, like a body gloxe

Great quality, but order a size bigger than you think, it's VERY tight.

I’m 5’10” and around 155 lbs. I normally wear a medium, but I wear a large in O’Neill rash guards, so I ordered a large in the Reactor wetsuit top. Unfortunately, the large was a little too short and too tight, especially around the armpit area. I don’t mind a wetsuit top fitting snug — it should fit tight for surfing — but this was restrictive enough that it just didn’t feel right. The sleeves and overall length also felt a little short on me. I exchanged it for an XL and am hoping that gives me the extra room and length I need while still fitting snug enough for surfing. Based on my experience, if you’re around 5’10” and 155 lbs and are between sizes, I’d recommend considering sizing up, especially if you have longer arms or a longer torso. I’ll update the review once I’ve tried the XL.

Very tight, warm and comfortable. Using for sea swimming.

Fits smaller than the size guide Im 178cm, 76kg Shoulder and waist measure in line with Medium Have had many wetties in the past - M in this is WAAAAY too small. Good product, Suggest go 1 size up from chart

Let all wet suits the sizing is way off. I realize they are supposed to fit snug as they stretch when they get wet but still there is no way I should fit a mens XXL. I am female 5'4" 145lbs and I ordered mens XL...they sent mens XXL and it fits me just fine. As a women I have hips so for a man the XL would've been fine. I normally wear mens medium if I get rash guards or Tshirts. The material is soft and dries very quickly (less than 12 hours).

INCÓMODA EXTRA GRUESA PEQUEÑA DEMASIADO AJUSTADA

Quality is good. Stick to the size guide. I followed the commenters and bought a size bigger and it’s too big.
