Meet the Yoofoss Baby Sleep Sack for 12-18 months, a fleece wearable blanket designed to wrap little ones in soft warmth without restricting movement. Crafted from 100% polyester, the fabric feels smooth and lightweight against delicate skin, while delivering a cozy layer for nightly rest.

Plush warmth with room to move
