Kaiya Baby Unisex Sleep Sack 1.0 Tog (18-36M) Wearable Blanket

Cozy, breathable comfort for little sleepers

The Kaiya Baby unisex sleep sack blends organic cotton, wool, and durable polyester to create a soft, loft-rich wearable blanket that stays fluffy wash after wash.

Designed for safe, peaceful nights, this sleep sack is certified by the US Consumer Product Safety Commission and features GOTS-certified organic cotton for skin-friendly breathability and a gentle touch against tiny sleepers.

Smart design for real‑life nights

An exclusive temperature sensing sticker sits at the chest, showing the surface temperature where the fabric meets skin. This helps you adjust layers without waking your baby, supporting calmer bedtimes.

• Double zipper plus anti-slip neckline for secure wear and easy diaper changes from the bottom.
• Loose leg area supports natural hip movement and comfortable kicking, while sleeves add warmth when needed.

Sizes, TOGs, and care you can rely on

Choose from S (0–6 months), M (6–18 months), or L (18–36 months). Four TOG options (0.5, 1.0, 2.5, 3.5) tailor warmth to room temperature and season.

Built for longevity, the sleep sack resists pilling and shrinkage, with less than 2% shrinkage after machine washing and guidance for low-heat drying.

Practical, everyday use

Ideal for bedtime, naps, or travel, the Kaiya Baby Sleep Sack keeps little arms warm while allowing natural movement and easy diaper access. The breathable fabric helps prevent overheating during restless nights.

Care and safety notes

• Machine wash cold (<40°C) on a gentle cycle; tumble dry low; iron on low if needed.
• Refer to the size chart to select the best fit as your child grows.

What to expect in daily use

From cozy bedtime routines at home to naps on the go, the sleep sack acts as a stable layer that keeps arms free for self-soothing and cuddle moments. A bottom zipper makes late-night diaper changes smoother without fully waking a drowsy baby.

• Single garment design reduces night-time fuss compared to separate blankets.
• Soft, breathable materials support comfort for sensitive skin.
