I previously bought the 6 inch short, but they felt like the ones that Magnum PI wore on the show, especially with compression short underneath. I returned them and got the 8 inch which is perfect. I played a couple hours of tennis and they were still dry to the touch, only wish there were more colors. The extra 2 inches made a difference both in fit and comfort.
First, the positives. The styling is basic and plain, fine for the gym or volleyball court. The material is sturdy, neat, compact and dries quickly. I could do without the white liner, but it's a plus if you wear the shorts as a swim suit (though I'd prefer the lining in a matching color). My main reservation about these is the VERY strong and tight elastic around the waist. I bought a size up, cause I like a roomy fit in activewear, but I had to ask my wife to remove some of the elastic. The shorts have a drawstring, so a much more relaxed elastic would suffice -- and would be far more comfortable.
