Are you heading out for a beautiful spring hike or ready to be the star of your own survival show? The popularity of buff headwear has skyrocketed with the popularity of reality television shows based on braving the elements. Worn as a top for women, as a scarf, headband or sweatband, or used in a pinch for whipping up your tent, buffs are a useful loop of fabric with seemingly endless functions. UV buffs protect the skin like sunscreen, while a buff headband helps tame hair and keep your hard-earned sweat out of your eyes. For runners, hikers and outdoor aficionados of all levels and ages, a good piece of buff headwear can be the difference between a great experience and constantly stopping to wipe away sweat, reapply sunscreen or, in winter, wrap yourself back up. eBay sellers have numerous styles, from lightweight summer buffs to warm fleece buffs for winter, with the added convenience of reliable shipping.
