New Easy Short Sleeve Swim Rashguard

I'm a melanoma survivor and bought four of these shirts in different colors. I love the look, the fit and the comfort. The shirts fit as I would expect. But, after two wearings, the oil blue and the white shirts developed very noticeable and extensive pills. The only thing I can attribute this to is carrying sand chairs on my back which have velcro straps. I felt the Velcro grab the fabric and sure enough there were pulls up and down the shirt. I have lots of sun shirts and I've never experienced this with them, and so far, I haven't developed a problem with the yellow or bright blue shirts. While I love the shirts, I wouldn't buy them again and I wouldn't recommend them to a friend.
