The HALO SleepSack Swaddle in the Multi Triangle cotton print is made from soft 100% cotton with a 1.5 TOG rating for moderate room temperatures. Its versatile 3-way design adjusts to baby's sleep style: arms in to reduce the startle reflex, hands-to-face for self-soothing, or arms out for an easy transition to the SleepSack wearable blanket when it is time to stop swaddling. An inverted zipper opens from the bottom for easy diaper changes, and the roomy sack design is recognized as Hip Healthy by the International Hip Dysplasia Institute. Replaces loose blankets for safer sleep. Discontinue swaddling when baby shows signs of rolling over. Small size for 3-6 months.
