Woolino 4 seasons sleep sack. Made of merino wool and fits babies from 2-24 months. Snaps on the shoulders and can be unzipped to let their legs out if they are walking. Really great option for all seasons as it regulates body temp. Constellation pattern. My son loved this sack. https://www.woolino.com/products/4-season-baby-sleep-bag-merino-wool-2-months-2-years-nightsky?variant=40257978859580
