The Woolino 4 Season Ultimate Baby Sleep Bag can be used all year round, thanks to its merino wool lining which is naturally temperature-regulating and moisture-wicking. It doesn’t have a TOG rating, and instead helps to keep babies cool on warmer evenings and snug on cold nights, reducing the need for different seasonal sleep bags. Named The Bump’s "Best Baby and Toddler Sleep Sack for All Seasons", the Woolino features double shoulder snaps, a two-way zipper and fits babies up to two years. OEKO-TEX 100 and GOTS certifications ensure the fabric is gentle on babies' soft, delicate skin.
