The i-baby Outlast® Baby Sleep Sack is a thoughtfully designed wearable blanket for toddlers, integrating smart temperature regulation technology to support natural sleep comfort. Crafted with Outlast® phase change material, this sleep sack actively absorbs, stores, and releases body heat, helping maintain a balanced microclimate around the child. The 2-way detachable sleeves offer flexibility for different seasons and room temperatures, allowing the sack to be used as a long-sleeve or sleeveless option as needed. The unisex design suits any toddler, and the bottom opening with legs makes it easy for little ones to stand and walk without restriction.

Made from breathable cotton-blend fabric, the sleep sack feels soft against the skin and ensures proper airflow. This sleep sack is sized for toddlers in the 2-3T range, accommodating growing children with a roomy fit that does not restrict movement. The double zipper system allows quick diaper changes without fully removing the sack, adding convenience for parents.

The fabric is machine washable, making it practical for daily use. At a very affordable price point, this sleep sack delivers excellent value for families seeking a high-performance, safe sleep solution. It works well for year-round use, especially in transitional weather when temperature fluctuations are common. The neutral color palette and simple design make it easy to incorporate into any nursery or bedroom.
