Musa Masala would like to thank Douglas Burns for this awesome post on the humble buff. Often used to save voices and throats at Everest Base Camp, buffs have been proving themselves in the mountains for years. (The recycling of moist, humidified air from your lungs helps stave off the dreaded Khumbu cough.) Doug is going to tell you about many other uses and we included a handy chart so you can play with yours to create your own unique look.
