Moisture-wicking Capilene performance polyester is quick drying and easy to care for. 3-snap closure that permits easy diaper changes. "Grow-fit" adjustable side snaps on bodysuit allow for growth. Pull-on pants feature a covered, elasticized waistband. Lap shoulders offer easy-on-and-off. Patagonia runs large. Love this little set! Good condition, just a little pilling from normal wear. Smoke-free home and open to bundles.
