The perfect minimalist natural fiber pillow for camping or every night sleeping. This pillow measures 7″ x 11″ x 4″ thick and is firmly stuffed with Eco Wool Batting. There is a small zippered opening through which stuffing can be added or removed to adjust the firmness level. This pillow provides excellent cervical support which is just the right amount for good alignment and stretching and decompressing the cervical disks and muscles. Designed mostly for back sleeping. You might want to get two and stack them for side sleeping (or place an article of clothing such as a sweater on top). Pillow inner is constructed from 100% French Twill cotton and covered with a soft merino removable cover (machine wash warm gentle).
