Hillbilly Impact Shorts Great hip and tailbone protection for all action sports including skateboarding, longboarding, skiing, snowboarding, and mountain biking. Features lightweight EVA foam padding, plastic tail bone protector, and breathable mesh fabric. Drawstring for extra adjustability and secure fit. If you are on the cusp between two sizes choose the smaller size if you prefer a tighter fit, or the larger size if you prefer a looser fit. We recommended a snug fit to prevent pads from moving upon impact.
