Great for swimming, surfing, snorkeling. Fits comfortably, doesn't chafe. Dries quickly once out of the water. Does NOT make grilled cheese sandwiches, much to my disappointment
I bought this shirt for a trip to Hawaii, so I could snorkel without having to apply sunscreen to my torso. The shirt protected me from sunburn. I would recommend this for sun protection.
Compared to the other Speedo, this one fits more like your typical T-shirt. One would feel comfortable running/exercising with this fit, though others may prefer a tighter fit for water sports.
