A sleep mask is an invaluable item for ensuring restful sleep in shared accommodations or during travel on the Camino. Choose a mask made from soft, breathable materials like cotton or silk that gently rest on your face without causing discomfort. Look for an adjustable strap to fit securely and comfortably around your head. A contoured design that allows for eye movement and reduces pressure on the eyes can enhance comfort. Ensure the mask effectively blocks out light to help you sleep better in bright or unfamiliar environments. A sleep mask can help you get the rest you need to stay energized for your journey.
