  • Sizing is ACCURATE
Size: Large Color: Black
Sizing is ACCURATE, regardless what others say. 90% of people always get the wrong size wetsuit. Suppose to fit tight with very little excess under arms and around shoulders…needs to be comfortably tight, not snug.

  • Exactly what I wanted. Maybe 5 stars? Or could it be better?
Size: XX-Large Color: Black
OK. First on the sizing. I truly don't get how their sizing chart for this can be wrong. For me 6'1" 192 pounds, I needed the XXL. I had just purchased a full suit of the same brand and XL was fine. But on to the product, it is exactly what I wanted. On my surfboard, I am mostly on top out of the water and was looking for something light and did not restrict my arms because I am older and my pop up totally sucks because of a bad hip. In cooler temps on my boogie board, I will use my full suit. But for surfing, this is exactly what I wanted. Light, not restricting and takes the chill off. ... show more

Size: X-Large Color: Black
The shirt is nice, but i would order it a size larger than you normally do. It runs very small

  • Order a larger size
Size: Large Color: Graphic/Black/C
This runs small. I have some similar tops and am usually a LT (large tall). I got the large and it was too tight and too small.

  • Does What I need
Size: Medium Color: Black
I am a Swim instructor who teaches year round at an indoor pool. The water I am in is 80 to 86 degrees all year round. Being a smaller framed persons after my 4th or 5th lesson that day I start getting a little cool. This shirt helps me start comfortable all day long. I would say it can ride up on the arms and waist if you are swimming hard laps and I haven't used it in open water so I don't know how it works in different temperatures. However, for light swimming in not real cold water it is perfect. ... show more

  • Perfect
Size: Medium Color: Black
I needed something to use on those very typical new jersey days when a 3/2 wetsuit is overkill, but a plain rashguard would give me the shivers. It has a nice tight feel when i wear it and looks great with board shorts. Make sure someone's with you when you need to take it of though. My wife had to rescue me out of it when i tried to take it off myself after a long surf session, i couldn't fight my way out of the shirt. Not bad putting it on when dry though. ... show more
