O'NEILL Men's Reactor-2 1.5mm Long Sleeve Top

Perfect for those crispy fall days where it’s too chilly to be shirtless, but would be too warm in a suit. Highly recommend.

I followed the advice of many other reviewers. Buy a size bigger than you usually wear. I usually get an LT (LARGE TALL) O'Neill wetsuit when I surf. I bought this in the size XL. It was snug like my full sized wetsuit. It feels well made. I've always like O'Neill wetsuits, so... I haven't used it for surfing yet since my trip to Hawaii isn't for a couple of months.

Good fabric, good design, well done but the size doesn’t fit with the bodyshape... a little bit tight in arms and waist.

I'm 6'3" 180 lbs got the XL, it fits well, it could be a little longer, but overall works great in the warm water of Hawaii with the cool breeze in the afternoon

Great purchase and fit!

I own several O’Neill wetsuits and gear, and usually love the brand—but this one really missed the mark. The fit is awkward, and it doesn’t keep you warm at all. Unfortunately, it’s the worst O’Neill product I’ve purchased so far.

The product is great, the size chart recommended a medium, I ordered a Large and could not get it on, an Extra Large fit perfect (2 sizes above the size chart). I exchanged it easily just in time for the warming Florida surf!

First, i wear a large in tshirt and got an xl fits great. Most of the reviews complain about it being toght but its a wetsuit you want it to be snug. Would recommend size larger than what you wear in a tshirt. Surf in huntington beach ca and it is a great addition.
