I have worn nothing but Give N Go boxer briefs for the past 4 years…in the office or on the trail…they are all I own. Last year I bought 3 pair of the new 9″ Sport Mesh on a whim and on sale. I really like the longer legs, but the material is decidedly a step down. Not only do I not like the feel of the fabric as much, but it started to pill between the thighs almost immediately. Over the past year, the pilling has increased slightly, but you can’t really feel it so I guess it is mostly a cosmetic issue.
To answer your specific question, I will not purchase the Sport Mesh again and will stick with the old school Give N Go.
