Very comfortable
I am 105 lbs and 5'3". I purchased this for myself, and it fit perfectly. It is my second Vapor fit Solar LS Shirt. I purchased the first on vacay and had to order a second one from the online store. There was a bit of variability in sleeve length and shared this with the company. Both sized fit me. I now wonder if the sleeves might have stretched out on the one I wore swimming during vacay? Hard to say. I would purchase this again.
