Finally figured out just how L O V E D they are :)
Bibs: moisture wicking, super soft polyester fleece with velcro closure. Machine wash cold, no bleach or fabric softener. Lay flat to dry.
Onepieces and tees: 100% ring-spun cotton (heather grey color contains polyester). Machine wash cold, inside out, with like colors. No fabric softeners. Non-chlorine bleach only (if needed). Tumble dry low or air dry for longevity. Cool iron, inside out, if necessary. Do not iron printed area, do not dry clean.
