tight fit like a wetsuit, but here''s a tip to slip it on easier when you''re already wet, pour some shampoo mixed with water into the shirt before wearing it and you will slip straight in.

I got this shirt for teaching aquatics classes as my students are the ones moving around the most and I stay relatively put in one place.  The pool temp is around 79-80 and it was too cold to be staying in one place, but this shirt actually had me sweating.  It's clearly designed for colder temps, but I'll take it.  Thanks!

I recently had to substitute for this item because O'Neill Thermo rash guard was unavailable. Overall, it was a good replacement & was in same price range.
I had purchased for a white water rafting trip I had taken where I knew the water would be cold. It did its job & kept me warm throughout the activity.
