Cozy, Safe, and Practical Sleep Wear for Toddlers

Meet the Unnivoll Fleece Baby Sleep Sack, a wearable blanket designed for toddlers 12–18 months. Crafted from 100% polyester microfleece, the fabric offers a gentle, skin‑friendly touch that stays soft wash after wash. This sleep sack is certified by the Consumer Product Safety Commission (CPSC), reflecting a commitment to safety alongside comfort. Its sleeveless design helps maintain comfortable warmth while allowing free arm movement, so your little one can settle in with ease.

Designed for the right indoor climate

The 1.0 tog weight is ideal for indoor temperatures around 68–75°F (20–24°C) in spring and fall. The ultra-soft plush interior paired with a breathable outer layer creates a cozy, dry feel through the night, so your baby can rest with fewer wake-ups.

• Soft, skin-friendly microfleece on both sides
• Breathable fabric that wicks moisture for dryness
• Lightweight warmth suited to mild indoor climates

Smart design for busy nights

Effortless diaper changes are easier thanks to a premium two-way zipper that runs from bottom to neck. A zipper guard at the top protects delicate skin from scratches, helping you change outfits or diapers without fully waking your little one.

• Two-way zipper for convenient night-time access
• Top-guard protects the chin and neck from zipper irritation
• Secure fit that stays put while baby moves

Comfort, safety, and flexibility in one wearable blanket

The sleeveless design reduces overheating risk and supports natural arm movement, while the roomy cut allows kicking without slipping off. This balance of warmth and freedom can contribute to a soothing sleep experience during changeable nights.

• Sleeveless design for better airflow
• Roomy yet secure fit to support hip movement
• Two-pack option for practical care and use
