When I had my first Buff, it was primarily intended for skiing: pull it over your head and wear it around your neck like a tube scarf. But it wasn't long before I got to know a wide variety of uses, including my new standard, which I call the "double buff".
The headband - the classic
Old but gold: simply gather it up and pull it over your ears. Keeps the wind out, your ears warm and the sweat out of your eyes.
The "Deep Sleep" mask
A variation of the headband that I love, especially on ferry trips or in the winter room. I simply pull the Buff down from my forehead over my eyes. Zack, the ultra-light sleeping mask is ready, which also holds the Oropax in place so that they don't get lost at night. This ensures a good night's sleep, no matter how much your camp mates snore or twinkle their headlamps.
The "double buff" - DIY balaclava
My absolute favorite when skiing, if you wear a helmet without the entire inner lining:
Pull the first Buff over your head as normal so that it fits loosely around your neck.
Fold the lower third of the second Buff inwards. Put this double-layered side on as a headband (ears covered, open at the top).
Now pull the scarf up from the back, place it over the headband and pull it over the chin (or nose) at the front. As the fabrics adhere perfectly to each other, nothing slips. This creates a modular balaclava that protects the ears from the cold in three layers, but still lets enough sound through.
