Kaiya Baby Unisex Sleep Sack 1.0 TOG for 6-18 Months | Wearable Baby Blanket

Cozy, Safe, and Ready for Nighttime Comfort

The Kaiya Baby Unisex Sleep Sack 1.0 TOG is designed as a cozy wearable blanket for babies and toddlers, sized for growing little ones. Its soft blend of organic cotton, wool, and polyester balances durability with a gentle touch, helping the sleep setup feel snug without sacrificing breathability. Built to endure regular washing, this sleep sack keeps its loft and plush feel after many cycles in the washing machine, so it remains a reliable layer across seasons.

Safety sits at the core of this sleep sack. It carries US CPSC safety certification and uses GOTS certified organic cotton, offering a breathable, skin-friendly surface that stays comfortable against delicate skin all night. While no sleep product can guarantee a specific outcome, many caregivers value the calm, breathable layer this wearable blanket provides during bedtime routines.

A standout feature is the internal temperature sensing sticker located at the chest. This clever detail shows the surface temperature where the fabric touches the skin, helping parents gauge warmth levels at a glance and adjust clothing layers without waking or disturbing the baby. It’s a practical touch that supports a peaceful night routine for both baby and caregiver.

The design emphasizes easy, thoughtful use. A double zipper with an anti-slip approach allows for simple diaper changes from the bottom while maintaining a secure neckline to prevent slipping or chin contact. The leg area is intentionally looser to encourage natural hip movement as babies grow, offering comfort and room for development while staying securely in the sack.

Careful sizing and warmth options let you tailor this sleep sack to your baby’s needs. There are three sizes: S for 0-6 months, M for 6-18 months, and L for 18-36 months. The warmth is adjustable through four tog options: 0.5 TOG, 1 TOG, 2.5 TOG, and 3.5 TOG, so you can match room temperature and seasons without layering up or down excessively. The result is a versatile sleep layer that can adapt as your child grows and your home environment changes.

Durability and easy care are built in. Kaiya Baby sleep sacks are designed to withstand millions of wash cycles, with shrinkage under 2 percent after machine washing and low heat drying. For best results, wash cold or at under 40 degrees Celsius on a gentle cycle, then tumble dry low and iron on a low setting if necessary. In daily use, the fabric remains soft, lofted, and comfortable against the skin, supporting a steady sleep routine.
