O'NEILLMen's Reactor-2 1mm Short Sleeve Top

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.

Great fit, it's comfortable to wear, warm enough (for colder days in Hawaii). Only down side I'd say would be the t-shirt tan, but it's the price to pay for wearing short sleeves and better paddle-ability.

Not a good fit despite following size chart.Had to return!Medium, looks more like Small.Quality and material seems good. No back zipper or front zippers.

My husband was looking for something to wear inside a swimming pool while teaching our granddaughter how to swim. Wanted something to keep him a little warmer in a cool pool since he would not be swimming to keep warm. I have seen mixed reviews regarding the sizing. We found the suit definitely fits on the small side. We went by the size chart to begin with and the top was tiny. Returned and ordered the next size. Even that seemed small. Tried XXL and that was too loose under the arms. My husband is 5'8" and around 150lbs. so not large.

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

This well made exposure swimming shirt is INCREDIBLY under sized. I bought a XXL ( since I wear a XXL t shirts) and when i received it I was amazed how small it is. I dont think it would fit on my seven year old grandson.

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.

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

Ordered Medium. Received one that on the stitched label says medium but on tag and bag says small?? Anyway, fits way too tight. And it is 1 mm, not 1.5. Disappointed with O'Neill

No me gusto ; No sella la entrada de agua por el cuello, si hay entrada de agua hacia la espaldaAnunciaba que el producto venía con un sello “gradual” y este sello NO existePague 100 dólares por un producto que NO voy a usar
