Halo Sleep Slack Swaddle, Size S

The best-selling SleepSack® swaddle. Designed for your little one’s comfiest sleep yet, this buttery-soft swaddle helps keep them cozy all night long for longer sleep sessions.

Just like all award-winning SleepSack® swaddles, our signature 3-way adjustable design allows you to wrap them the way they sleep best — arms in, hands-to-face, or arms out. Adjustable hook-and-loop fasteners create a snug fit, while the 2-way zipper makes late-night changes easier. And with a roomy, hip-healthy sack design, it’s thoughtfully crafted for comfort and healthy development.
