The fabric uses fleece, so it's stretchy and feels good against the skin. The area under the chin can be adjusted with Velcro, allowing for 2-5cm of movement. It will be shipped compressed, but since it uses synthetic cotton, it will return to its original shape if you adjust it after opening. *Please refrain from price negotiations as each item is handmade. SS size: Face circumference 30-34cm (red line) We also have S and M sizes available, so please comment if you'd like to inquire about them.
