O'NEILLMen's Basic Skins UPF 50+ Long Sleeve Rash Guard

I got this in the mail today and it is perfect. Here's my measurement for your reference: neck circumference: 14.5 inches; shoulder width: 19 inches; chest: 36.5 inches; waistline: 33 inches. I am 5'8" tall. For slim people like me this fits perfectly. Of course it clings like a second skin so if you have a bulging beer belly, it might be a little too tight around the belly. Since I just got this, I haven't trued it in wet condition but I guess it would be okay.This is my second Oneill wetsuit. The first one I got was a large because I followed the suggestions of others to go a size larger. It was a little too loose for me. The arms are sagging and too long, the neck is loose and the chest is loose.

it is performance style and it acts as the second skin as the it advises, so by design it will be tight but it stretch for your movement. I am in right in middle of medium and large. I picked medium at the end because the large gives less second skin feel, creates more "wrinkle" when wearing it and does not give extra room for movement (it actually does not need to as the medium stretches to all my needs). hope it helps.

I'm 5ft 10 inches, 160 pounds, athletic build and am happy with size M for surfing. Its slightly difficult to put on and take off, but not too bad once you get used to it. It's comfortable while surfing and doesnt flap around in the wind. I got a mild armpit rash the first few times I wore this, but no rash the last dozen times I've worn it. A size large might be more comfortable if I were only wearing it while hanging out at the beach and doing light swimming. Good price and quality.

I’m 5’ 8” at 165 lbs and I bought a size Medium. Use it for snorkeling and free diving, fits perfectly, keeps me warm, and then keeps me cool when I get out in the direct sun when the breeze hits. Easy to wash off and breathable. Would buy again and suggest to others.

I read a number of the reviews on this product before I bought this shirt. One thing that keeps coming up is the sizing. I'm 6'1" and weigh 175 pounds. I bought a medium. Most of the time that size of whatever shirt works well, sometimes it's too small. It fit tight but I'm told rash shirts should. I can swing my arms around and stretch without any problems. I'm going to be using it to snorkel in. I have a VERY small 'gut' but this shirt does make it show. I wear cycling clothes when road riding (these shirts and shorts need to be tight for proper wicking action and to be non skin rubbing) and those shirts (depending on the brand) sometimes accent the gut too. I wear a medium for cycling as well. I'm just waiting to try it now.Update: I'm back from Hawaii. This shirt worked very well! I happened to drift through some jellyfish, a bunch of them. I didn't get stung one time! Not sure if this shirt helped, but I'm sting free. I stayed warm too in this shirt, warm not hot. I bought mine black in color.

I have bought several of these over the last 7 years. As a former competitive swimmer, I prefer the performance fit, as it’s like a second skin. It makes my workouts a little tougher and creates the feeling of being deeper in the water.It is a bit difficult to remove when wet, but the trick is to work it up from the bottom to your chest and then pull it over your head.

This rash guard is a second skin, in the sense that it is so tight that once you wear it (if you are able to) you won’t be able to take it out...OK, seriously, it is too tight: I usually wear S t-shirts and ordered an M, and still it was quite difficult to get inside this rash guard. Once inside it is not that uncomfortable: I can move my arms in any direction without any problem, but I feel some compression on my chest, and when I try to get out, again it takes forever.To get an idea on how tight it is watch my first picture, the green t-shirt is a European S, (so an XS in USA).I also has a tag that says “The protection [from sun] offered by this item may be reduced with use or if STRETCHED or WET”. Seriously? How and when am I supposed to wear it?Unless you are looking for something extremely tight I would advise buying a couple of size bigger or opt for a different rash guard, the one I am using now ( Body Glove Men's Long Sleeve Fitted Rash Guard ) is definitively much more comfortable, it is more soft and stretchy and, even if it is really tight, it is easier to wear it and to take it out.

The sleeve is a little longer but works out as I use the extra length to cover my watch while doing activities in the water.
