Yoofoss Baby Sleep Sack 12-18 Months – 100% Organic Cotton Wearable Blanket, 2-Way Zipper, TOG 0.5 (3-Pack)

A softly breathable wearable blanket for growing toddlers

The Yoofoss Baby Sleep Sack is designed for little movers aged 12-18 months. Crafted from 100% organic cotton and GOTS-certified, it offers a gentle, breathable surface that helps your baby feel naturally comfortable as they drift toward sleep. The lightweight fabric is ideal for warmer nights or layered sleep setups, giving you a sense of ease without sacrificing a cozy night’s rest for your child.

Key comfort and safety features are built with nighttime routines in mind. A smooth 2-way zipper runs from top to bottom, making midnight diaper changes smoother while your baby stays snug. Interior zipper guards and a top zipper cover protect tiny skin from zipper contact, reducing irritation and nudging the sleep environment toward calm and consistency.

Fit and freedom matter. Arm and neck openings are sized for a secure, comfy feel, and the leg area is roomy enough for natural movement without the risk of the sack riding up. This thoughtful design supports your baby’s ability to move and explore while staying warm throughout the night and potentially supporting healthy hip positioning as they grow.

Practical, family-friendly, and versatile, this 3-pack ships with three colors that suit both baby boys and girls. It’s available in four sizes to grow with your child, from S to XL, so you can keep choosing the right fit as your baby develops. Whether you’re stocking up for registry essentials or simply ensuring night-after-night comfort, these sleep sacks bring flexibility to bedtime routines.
