The front of the bib is cotton, back is flannel or fleece. I use a lightweight, absorbent inner lining that wicks moisture away and keeps your loved one dry. Patterns are age-appropriate for more mature wearers. Small size is great for toddlers through tweens. Large size accommodates teens and adults. Neck has two sets of snaps to ensure a perfect fit. Double stitched for durability. Made with soft fabrics that will not irritate sensitive skin.
