It offers exactly what it promises. I got it in the size I usually take for regular t-shirts and it fit perfectly.

Excellent sun protection. It has a snug fit and sticks to the body very well when coming out of the water. I cannot speak for durability as I have been using it for about a month and so far I have no complaints. It dries relatively slowly after coming out of the water, although this is a positive aspect during hot weather. Personally, I consider it a very good choice.
