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 - there is some pilling from normal wear, especially on the knees and bottom cuffs of the pants. Also on the back left leg there is a little small green stain that I only now just noticed. See photos. None of this affects the warmth but the price is adjusted accordingly. Smoke-free home and open to bundles.
