HALO SleepSack Wearable Blanket 0–6 Months, 100% Cotton Interlock, TOG 0.5, Baby Blue, Small

Safe sleep, wrapped in cotton comfort

Halo SleepSack Wearable Blanket offers a simple, comforting alternative to loose blankets in the crib. Trusted by hospitals and families alike, it stays in place through the night, helping little ones settle with fewer movements that wake them up. The result is a warm, secure feel without the bulk of a traditional blanket.

Crafted from 100% cotton interlock with a lightweight TOG 0.5, this sleepsack is breathable and soft against delicate skin. The double knit construction provides just the right amount of gentle stretch, so the fabric moves with your baby as they shift and stretch during sleep.

The design is hip healthy, a distinction recognized by the International Hip Dysplasia Institute, which reflects thoughtful attention to healthy hip positioning. The sleeveless silhouette helps reduce overheating, while the neck and arm openings are sized for a snug, safe fit. A practical bottom-opening zipper makes diaper changes faster and quieter, so you can return to soothing routines with less disruption.
