Lole Whiteheaven Long Sleeve Rashguard

I love the jade color with the floral print. I am an ocean kayaker and need sun protection in the summer. I am on the east coast so it gets really hot here. I like the zipper for easy entry/exit and cooling down. I ordered a medium and it fits just right. I am 5'4" 108 lbs. I did not want it skin tight, but not big...just a little room for some air movement. I didn't want it to fit like a sausage skin, but yet be comfortable to swim in and not make me feel compromised in the water. The only thing that could be better is if it was a tad thinner. I am putting feels too small because I normally wear a small or XS and had to order a medium in this.
