I've got several styles of SAXX and they're all awesome. SAXX are superior to other underwear because there are mesh panels in the to keep your sweaty legs from sticking to your most sensitive areas. The parallel side panels create a layer of material between your legs and sack so you'll never have to unstick your junk from your thighs again. And unlike regular briefs, Saxx underwear doesn't bunch constrict your boys into a tiny pouch--they get to hang as low as they want.
SAXX Vibe features lightweight, breathable viscose material. I wear the Vibe for running, biking and hot weather activities - any time I need ultra wicking and no sticking.
Finally, the Vibe looks great! My girl loves the colors they come in.
The mediums fit my 32 waist perfectly.
