Yoofoss Baby Sleep Sack 12-18 Months | 1.5 Tog Sleeved Wearable Blanket, 2-Way Zipper

Yoofoss Baby Sleep Sack 12-18 Months — Soft, Safe, and Cozy Wearable Blanket

Meet the Yoofoss Sleep Sack, a long-sleeve fleece wearable blanket designed to keep little ones snug through naps and night sleep. Made from soft, lightweight 100% polyester, it provides a gentle cocoon that moves with your baby as they wriggle, reducing drafts and creating a calm sleep environment without overheating.

Safety and Quality You Can Trust

The sleep sack is certified to meet Consumer Product Safety Commission (CPSC) standards, reflecting a commitment to safety and coziness. The fabric feels soft and smooth against tiny cheeks, offering warmth without bulk, and the sleeve design preserves natural arm movement while minimizing exposure to chilly air.

Plush Comfort Meets Roomy Flexibility

An 8mm plush interior adds a comforting touch, which can help babies settle more quickly. The sleeve design keeps arms free for playful motions, while the roomy cut allows kicking and movement, supporting healthy hip development as your baby grows.

Practical Design for Easy Nighttime Changes

The hidden 2-way zipper features zipper protection to guard sensitive skin. Double zippers enable fast dressing and nighttime diaper changes, while high-grade zippers glide smoothly to prevent snags during late-night tasks.

Ideal Temperature Range and Seasonal Use

With a 1.5 Tog warmth level, this sleep sack is suited for environments around 69–73°F. It’s adaptable for autumn, early winter, and spring, or for naps in cooled rooms where a gentle layer is desired for comfort.
