Yoofoss Baby Sleep Sack 12-18 Months – TOG 2.5 – 100% Organic Cotton

Meet the Yoofoss Baby Sleep Sack for 12-18 months, a wearable blanket crafted from 100% organic cotton with a soft inner fill. GOTS certification signals a commitment to gentle fabrics and responsible production, helping you feel confident about what touches your baby’s skin. This sleep sack replaces loose blankets in the crib, offering a secure sleeping layer that moves with little one as they drift toward dreamland.

With a 2.5 TOG warmth rating, it’s designed for cooler rooms—think early mornings or winter nights—at typical indoor temps around 50 to 68°F. The sleeveless silhouette and bell-shaped bottom provide generous room to stretch legs and wiggle hips, supporting safe, natural sleep movements without overheating or restriction.

Practical design features matter at night. A sturdy 2-way zipper runs from top to bottom with a protective garage that shields the chin and cheeks from rubbing, and the zipper can open from the bottom for quick diaper changes. Four sizes adapt to your growing child, ensuring a good fit that stays in place without riding up near the face.

Care is built in for busy families. The fabric withstands hundreds of washes with minimal shrinkage, preserving softness and fit over time. This sleep sack is easy to launder, quick to dry, and ready for another night of peaceful sleep, in your home or while you travel.
