Yoofoss Baby Sleep Sack 12-18 Months – 100% Organic Cotton, 2-Way Zipper

Cozy, breathable sleep space for your growing toddler

The Yoofoss Baby Sleep Sack for ages 12-18 months is crafted from 100% organic cotton, offering a soft, breathable touch that feels gentle against sensitive skin. GOTS-certified fabric signals a commitment to high-quality materials and responsible production, giving you a tangible sense of comfort every night.

Designed as a wearable blanket, this sleep sack provides warmth without restricting movement. A smooth 2-way zipper runs from top to bottom, paired with an interior zipper guard and a top zipper cover to minimize friction on delicate skin during diaper changes. The result is a practical, user-friendly option for bedtime routines that feels calm and reassuring for both baby and caregiver.

Fit, safety, and comfort in one lightweight design

The arm and neck openings are sized to provide a secure, snug feel while leaving room for natural movement. The leg area is thoughtfully sized to allow kicking and movement without the sack riding up, helping your little one stay cozy through the night. This design supports a comfortable, supported posture for active babies who are still learning to move on their own.
