Initially designed for off-road motorcyclists, Buff's headwear makes my life better. Helmets are easier to put on, the back of my neck not exposed to the sun! Other sports benefit too!
A simple, stretchy polyester tube that you can stretch over your head or wear like a scarf around your neck. Buff makes them in tons of colors and styles. I wear one over my whole head, covering my neck, under my motorcycle helmet, and under the neck seal of my Fusion drysuit. They come in handy hiking and camping too!
