    • Wow, This Really Works
Size: X-Large Color: Black
I've never bought a rash guard or insulative top before, but we just bought a new house with a big pool and it's just too cold outside of the summer months and too expensive to heat. I'm a bigger guy and the XL fit great. It's thick and spongy but not heavy. I had no idea what to expect. It does not constrict any movement. I kind of look cool wearing it, and even gives me a little slimming look, if I do say so myself. I can easily get into a cool pool and at first I feel just a bit of the coldness, but in 15 or 20 seconds, its great! I spend 30 to 60 minutes in the pool after 5PM and it never loses the insulating effect. It's easy to get off and it dries super quick, just letting it hang over the balcony. I'm not sending a picture, because I don't think anyone wants to see that, BUT I for sure recommend this. Saw ones that were TONS more expensive. Don't know how much better those are, but like I said this one works GREAT!!! ... show more

    • Great fit. And it works. By it's self or under a wetsuit I stay warm!
Size: Medium Color: Black
Perfect for those days when it's not cold enough for a wetsuit, but you still want to stay warm! And when it's really cold, I wear it under my wetsuit for a little extra warmth!

    • In between a 3/2 and board shorts
Size: X-Large Color: Black
I bought this for surfing Socal summer, it's thick enough that it almost feels like a 3/2 but thin enough that it feels like a rash guard. Good middle ground. The inside has a fleece like lining and it kept me warm and cut the wind chill. Since it has that fleece lining it does feel like it gets a bit heavier once in the water but still has enough flexibility. Very happy with this purchase. ... show more

I had a hard time deciding, im convinced there are no picture reviews with sizes on all of the internet. I'm 5' "8 150lbs not really muscular I went with size large, if you were muscular or slightly taller def a large, if you were my size maybe slightly smaller and wanted it to wear under a wet suit perhaps a med. I am using this for a chilly indoor water park but am very happy with the size goes past the top of my shorts plenty long enough and the connector is a cool extra and the fleece inside is very nice, soft and not too thick what you'd expect for a hat or shirt/pants to have a lining. For me I'm very happy with size and fit. Hope this helps ... show more

    • Fits Snugly, Gets Heavy
Size: Large Color: Black
The O'Neill Men's Thermo X Long Sleeve Insulative Top is designed to fit tightly, so consider buying your normal size. It provides good insulation, but it can get heavy when wet with water. Overall, it's effective for keeping warm in colder conditions.

    • Use in chlorine pool for water aerobics - works great!
Size: XX-Large Color: Black
I wear this under my swimsuit tank top (I'm a woman) to keep my upper body warm in the winter months while doing water aerobics and water walking in a heated chlorinated pool. So far it is holding up just fine - I have worn it during 24 1-hr sessions and it has not faded, has not stretched, nor is it showing any signs of breaking down. It keeps my upper body and arms comfortably warm. Even though the Thermo-X fabric is quite stretchy, these tops run very small. I am a fairly large woman (usually wear Woman's 2X) and needed to buy a men's 2XL. Because it is a men's, it is a bit snug at the hips, but the rest of it fits well. Fair warning: once wet it is a bit hard to take off, but once you get one arm out of a sleeve, getting the rest of it off is pretty easy. ... show more

    • So comfortable. Not bulky, but very warm like wearing a light blanket.
Size: Medium Color: Black
Love it! Very stretchy and non restrictive. Just the right thing for those seventh degree days out there when there is some wind.
