Favourite pair of underwear for running! These are extremely comfortable - soft fabric, soft waistband, nothing digs in or irritates at all. They're great for warm or cold weather as they wick away the sweat. Slight shifting as I run, but I think I might have bought a size too large. Will try the small next time and see if there is a difference. Size runs slightly large, as I am normally a medium in most underwear brands - these are just a touch too loose.
I love these boy shorts. They keep the tush toasty when it's cold out and cool when it's warm out. The cut is awesome for those of us who don't like their underwear in their bum crack. I've done all the sports I do in these undies — x-c skiing, running, cycling, walking, beer drinking — and these stand up great. They're the only IB item I've ever bought not on sale, I like them so much. Fit is TTS.
