I LOVED this UV Rash Guard! I play beach volleyball and had a tournament back to back weekends. After the first weekend I got a HUGE sunburn and was afraid to be out in the sun again the next weekend. This was a lifesaver! The material feels liek a swim suit but it was thick enough to not be see-through. I used it more as a shirt with my bathing suit under. I am 5'8 about 165 lbs and the large fit perfect:) I loved how there was a zipper to either show a bit of the swimsuit or just cover up all together. I just finished washing it after a weekend in the sand and all the dust came off also:) Would highly recommend it!
