I like wearing something under my helmet almost year-round. The Buff is quite long but otherwise perfect, so I wear half a Buff in summer or a whole one folded double when it gets colder. I pull it down around my neck first, then pull it up again over my hair until the front end meets my hairline, then I tuck the rear end at the nape of my neck under itself a couple of times so it snugs down. Easy and sleek.
