Gaiters are the clothing equivalent of the Swiss Army knife. They can be used in many different ways both for hot and cold weather. They come in several materials (merino wool, fleece and synthetic fibres) and different lengths depending on what they're used for.
For cold and mountain climates, a gaiter will keep the head and neck warm and dry. When placed in front of the ears and airways, it limits the direct entry of cold air. It helps to prevent the accumulation of sweat on the face and allows to clear the condensation of the breath. It also protects from frostbite. Be careful when wearing the gaiter in the mountain pass mode, as it can be scary for other people who don't know your intentions. We recommend that you uncover your face and explain that you are a pilgrim. There are countries where it is forbidden to cover your face.
In hot climates, the gaiter can serve as protection against solar radiation and can act as a dust mask *. When wet, it can be used to lower body temperature when worn on the neck, head and wrists.
At the hostel, the gaiter can serve as a eyemask to block out the light. By tying the ends and filling it with clothes, it can be used as a pillow. On colder nights, it can keep your head warm.
* Important note: a gaiter does not serve as a protection mask against any type of virus.
It is not easy to walk alone in the country without musing upon something
