Yoofoss Baby Sleep Sack 6-12M | 1.5 Tog Fleece Wearable Blanket with 2-Way Zipper

Soft, Safe, and Snug Nighttime Comfort

Meet the Yoofoss Baby Sleep Sack designed for babies aged 6–12 months. Crafted from 100% polyester, this fleece wearable blanket wraps your little one in a gentle, lightweight embrace that feels like a cozy cocoon. The fabric is soft against tiny skin and moves with your baby through the night, helping them settle into calm, restorative sleep.

A notable touch is an 8 mm plush liner that adds a subtle, comforting texture. This small detail can help soothe fussy moments and ease transitions between sleep and wakefulness, while the overall design keeps baby warm without overheating.

Key features that support calm nights

• Safety first: 100% polyester fabric with CPSC safety certification to support a secure sleep routine.
• Room for movement: a roomy cut allows kicking and natural hip development while maintaining warmth.
• Hidden 2-way zipper with protective backing to prevent skin contact while enabling easy nightly changes.
• Sleeves and 1.5 tog warmth: long sleeves help with warmth in moderate climates (69–73°F) for autumn, early winter, spring, or cool air conditioned rooms.

• Care and value: machine washable and available in a 2-pack set with multiple sizes for growing babies.

Real-life use and considerations

In everyday moments, this sleep sack pairs with a simple bedtime routine—a gentle, swaddle-like feel that still allows arm movement for self-soothing. Parents appreciate quick diaper changes thanks to the hidden zipper, especially after late feedings or night trips to the nursery.

Care, fit, and sizing

Choose from four sizes—S, M, L, XL—so you can match your growing baby. The 1.5 tog and sleeve design strike a balance between warmth and comfort, and the two-pack option makes it easy to keep a ready-to-use sack on hand.

Seasonal transitions and convenience

Ideal for transitional weather, this sleep sack is designed to keep little one cozy during autumn and spring, as well as in air-conditioned rooms during warmer months. The long sleeves offer warmth without restricting movement, supporting a natural sleep rhythm through the night.
