A buff is one of the most versatile pieces of headwear for the outdoors. It is basically a tubular bandana and is usually made from a stretchy, synthetic material like spandex or lycra.
Buffs are useful because they serve many functions but are still light weight and packable. They can block UV rays, stop wind burn, provide warmth, and wick away sweat.
We could list all the ways you can use this inexpensive piece of gear but we better show you.
Don't take our word for it. We borrowed Henry's video to demonstrate the many ways it can be worn.
