Overview

Meet the Woolino 4 Season Sleep Sack, a versatile wearable blanket crafted for year‑round comfort. It combines a luxuriously soft Australian merino wool lining with a GOTS certified organic cotton exterior, offering a naturally breathable, temperature‑regulating environment for your baby.
