Toddler Sleep Sack, Infant Sleep Sack with Removable Sleeves

Our sleep sack for babies is designed to be a positive sleep association - a "lovey" that helps your little one fall asleep faster and stay asleep longer, even when traveling. This sleep bag promotes the development of good sleep habits essential for proper growth and development, allowing both you and your baby to sleep better.

Crafted with intelligent two-way temperature control technology, the sleep sack utilizes Microencapsulated Phase Change Material (PCM) fillers. This innovative material can undergo phase conversion, absorbing and dissipating heat to automatically adjust the body surface temperature in response to ambient temperature changes, ensuring your baby sleeps at the ideal temperature.

Offering superior quality and thoughtful design features, this sleep bag is made with 100% organic cotton lining and outer fabric. The fill is a blend of 78.6% polyester and 21.4% Viscose Fiber (USBETTAS & Tempsense fiber), which are hypoallergenic, breathable, and colorfast. The fabric is exceptionally soft, with no shrinkage or pilling after washing, thanks to the use of 40S combed cotton and compact Siro spinning technology.

The sleep sack's design includes several key features for your baby's comfort and safety. The arm and neck openings are sized for a perfect, secure fit. The detachable sleeve design allows you to convert the bag between long and short sleeves. The stretchy, roomy bottom provides ample space for your little one to sleep comfortably in the frog position and move freely. Additionally, the two-way zipper makes diaper changes more convenient.

Wearing this all-in-one sleep bag, your baby will be unable to stand up or climb out of the crib easily, promoting a safer sleep environment. This sleep sack is an essential baby item, making it an ideal choice for baby showers or baby registries.

For best results, we recommend hand-washing the sleep sack rather than machine washing. Please be sure to refer to the size chart before ordering to ensure a proper fit. Each sleep sack is backed by a 30-day money-back guarantee, so you can try it with confidence.
