Woolino sleep sack for ages 2-24 months. Both my kids loved these from 2 months to 30 months (unzip the bottom for a dress like blanket!). They are in surprisingly good condition for their heavy use. Link with white polka dots. price reflects wear and tear, including a few small stains and some holes were a teething toddler chewed (see pic). The woolinos are made of merino wool, have a two way zipper and shoulder snaps, and a carseat buckle hole. They have armpit snaps to adjust sizing for age.
