Kaiya Baby Unisex Sleep Sack – 0.5–3.5 TOG Wearable Blanket (0-36 months)

Cozy, safe sleep sack for babies and toddlers

The Kaiya Baby Unisex Sleep Sack is a wearable blanket designed to keep little sleepers comfortable from nap time through the night. Its fabric blend—organic cotton, wool, and polyester—offers a soft touch, lasting loft, and reliable durability that holds up to everyday wear and washing.

Certified safety meets skin-friendly comfort

Certified by the US Consumer Product Safety Commission and built with GOTS-certified organic cotton, this sleep sack prioritizes breathable skin contact and a gentle touch. The result is a fabric that stays comfortable against delicate skin while moving with your baby’s sleep rather than sticking to it.

Temperature-smart design for calmer nights

Kaiya’s chest temperature sticker gives a quick surface read, helping caregivers adjust layering without disturbing bedtime, supporting a peaceful night environment and fewer wake-ups due to uncomfortable layering decisions.

• Breathable fabric blend supports steady air flow around tiny bodies
• US CPSIA certification and GOTS-certified organic cotton for safety and comfort
• Internal temperature sticker aids easy layering decisions
• Double zipper with anti-slip details for smooth, quick changes
• Secure neckline and roomy leg area support natural movement and growth

Designed for real nights and busy parents

The bottom zipper makes late-night diaper changes simpler, while the neckline prevents shifting the fabric onto the baby’s chin. A loose fit around the legs fosters natural hip movement as your child grows, while still keeping them snug and secure.

• Bottom zipper enables easy diaper changes without full undressing
• Two-way zipper and anti-slip neck design simplify dressing and removal
• Three sizes (S, M, L) cover newborns to toddlers
• Four TOG options (0.5, 1, 2.5, 3.5) adapt to different room temps
• Built to withstand millions of washes with less than 2% shrinkage

Caring for lasting softness

For best results, machine wash on gentle cycle under 40°C, tumble dry low, and iron on low if needed. With proper care, the loft and softness of the fabric can persist over time, supporting continued comfort night after night.
