Color: Black Size: Large
My husband works outside in all weather conditions. When one really rainy day, his coworker told him about these O'Neill shirts he got for this specific weather condition. So we did the "try before you buy" because its a lot for one shirt. Think of a wetsuit. Wetsuits keep you warm even when you're in cold waters. this helps too with rain! By husband wore this under all his layers, even had rain gear on for the day when that day it was supposed to rain all day long. He said his rain gear only keeps him dry for so long and then its useless because your layers get drenched, heavy and cold too. He raved about this shirt and how it not only kept him warm, but he felt more dry too! Keeping your torso warm when its cold out is crucial. Needless to say we bought it and kept it. True to size. if you're a large and usually get a medium for underlayers, don't. get the large and itll fit you snug like a medium undershirt would. these are true to size. only con; at his armpits where his arm creases, there was chafing. Cant avoid that so we will have to put some tape or gauze of some sort on him before he wears it so he doesn't chaff there with this shirt. ... show more

    • Good to keep the chill off

Nice layer for early morning spring sessions. Good for water temperature around 65

    • Too small
Color: Cadet Blue/Graphite/Cool Grey Size: Medium
I’m 5’8”, 145 lbs and a medium was way too small. According to the size chart it should have been loose on me but I could barely breathe once I got it on and getting it off was a two-man operation. I sent it back and ordered a large.

    • Warmth provided
Color: Black Size: Large
We swim year round and my husband needed something to keep his shoulders warm and this does the trick. Well made and good thickness for providing protection from the cold

    • Size Too Small
I also have been surfing for quit a long time, over 40 years, and this wetsuit top is way too small. I am 6'2", 170lbs., and wear L or LT for all brands, including O'Niell, but the large that I ordered fits like a tight medium. I could barely get it on in front of the bathroom mirror, before my wife laughed at me. I will reorder this suit in an XL (first time I've ever worn any item in XL) and see if that works. ... show more

    • Perfect for mid-70s water in Maui
Color: Black Size: Large
First time user of a product like this. I've snorkeled once or twice and loved it, but hate being cold. Got this for a week-long trip in Maui and it was absolutely perfect. Water was about 75° F I think, and I was totally comfortable in this. Could have stayed out for hours. Size L was perfect for me at 6'4", 185 lbs. ... show more

    • Sizing is ACCURATE
Color: Black Size: Large
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.
