Unnivoll Baby Sleep Sack 18-24 Months | 1.0 Tog Cotton Wearable Blanket

Meet Unnivoll — a wearable blanket built for safe, cozy nights

Designed with your baby’s comfort in mind, the Unnivoll Baby Sleep Sack uses 100% cotton to deliver a soft, skin-friendly touch on sensitive skin. Certified by the Consumer Product Safety Commission (CPSC), this sleep sack aims to create a secure sleeping environment while keeping your little one comfortable through the night.

The 1.0 Tog weight is ideal for indoor temperatures around 68–75°F, making it a versatile choice for spring, summer, and fall. A preshrinking process helps keep the fit consistent: shrinkage stays under 2% after machine washing and low-temperature drying, so you can rely on a durable, practical garment that grows with your baby.

Smart design that fits real life

With a premium smooth two-way zipper, diaper changes are simpler and quieter, even in the dark. A protective zipper guard at the top guards delicate chins from scratches, reflecting attention to baby comfort during nightly routines.

Roomy, secure, and movement-friendly

The sleep sack offers ample space for kicking and leg movement while staying on your little one. The sleeveless design helps prevent overheating and allows free arm motion, contributing to a feeling of warmth without bulk. This thoughtful shape supports a natural sleep posture and helps keep the blanket in place as your toddler moves.

Sized for growing toddlers

Four sizes ensure a better fit as your child grows: S (0–6 months/10–18 lb), M (6–12 months/16–24 lb), L (12–18 months/22–28 lb), XL (18–24 months/26–34 lb). The unisex style suits both boys and girls.

Care that keeps everyday wear easy

Machine washable with low-heat drying, the fabric maintains softness and durability for daily use. The 1.0 Tog weight makes layering straightforward, so you can adjust warmth as the room temperature shifts.
