Yoofoss Baby Sleep Sack 12-18 Months | 1.5 Tog 100% Organic Cotton Wearable Blanket

The Yoofoss Baby Sleep Sack is a versatile wearable blanket designed for infants in the 12-18 month range. Crafted from 100% organic cotton layers with a soft polyester fill, it balances gentle warmth with breathable comfort for sensitive skin. The garment is GOTS certified, reflecting a commitment to eco-friendly materials and responsible production without compromising on softness or safety.

Thoughtful design for growing babies

The sleep sack adopts an ergonomic bell-shaped bottom and a sleeveless silhouette. This combination creates ample hip room for natural movement while helping regulate temperature so little ones stay comfy through the night and nap times.

• Ergonomic bell bottom supports healthy hip movement and a roomy seating area.
• Sleeveless design gives babies greater flexibility and reduces overheating risk.
• Two-way zipper with a snug zipper garage enables fuss-free diaper changes while the baby remains undisturbed.

All-season warmth without bulk

With a 1.5 tog rating, this sack is designed for moderate temperatures (roughly 69–73°F / 20–23°C). It’s an ideal option for autumn, early winter, and spring, or for maintaining consistent warmth in air-conditioned rooms during warmer days.

• Keep baby snug in transitional weather without layering bulky blankets.
• Use in sleep spaces that swing between different temperatures for steadier comfort.

Durable, easy to care for

The Yoofoss sleep sack is built to withstand hundreds of washes. It cleans up easily and retains softness with minimal shrinkage—less than 3% after machine washing and drying on low heat. It’s designed to fit correctly when sized to weight ranges.

Care tips and sizing notes help you choose confidently: S (0–6 months), M (6–12 months), L (12–18 months), XL (18–24 months).

A practical, cozy choice

Living with a calm, well-rested baby matters. The Yoofoss sleep sack pairs natural fabric with thoughtful details that support peaceful nights and relaxed days, providing a reliable layer you can trust for seasonal use and daily routines.
