This rashguard shirt is exactly what I wanted---a shirt to ward off the sun while swimming laps. It's extremely comfortable to wear and to swim with. The neck line is not too high (as opposed to the feeling you sometimes get with a wetsuit) and the design around the shoulders is very comfortable. I swam a long workout the first day wearing this shirt and forgot I was wearing it.

Sizing seems exactly right, but they are very stretchy and so are probably forgiving. The product literature says that you can lose some of the sun protection effectiveness if the shirt is stretched too tightly. So take that into consideration when choosing a size.

hi, i will be wearing the shirt under a triathalon wetsuit;  i've tried it already in the ocean (cold) and it seemed just fine.  no drag.

I teach swimming lessons throughout the day and this is a good way to keep me under wraps and avoid getting too much sun

I bought this to keep me warm in an outdoor pool in the winter.
Works great! A little drag. An article I read on the internet told me to order a size larger than I wear. NOT. It would be perfiect if I had followed SwimOutlets sizing chart. But I still love it. It keeps me as warm as I want to be.
