HALO Micro-Fleece Sleepsack Swaddle - 3-Way Adjustable, TOG 3.0, Hip Healthy | Animal Action | Small (3-6M)

Cozy warmth, flexible swaddling, and a design that grows with your baby

Meet the original HALO SleepSack Swaddle, a hospital-trusted design used by over 1,800 hospitals and trusted by more than 30 million parents. Made from soft micro-fleece and rated TOG 3.0, it provides warm coverage in cooler nurseries (61–64 °F) without loose blankets.

Three ways to swaddle as your baby grows

The 3-way adjustable wings let you tailor the wrap: arms in for secure wrapping, hands-to-face for comforting self-soothing, or arms out as little ones learn to move.

• 3-Way Adjustments: arms in, hands-to-face, or arms out to match your baby’s sleep style.
• Warm, breathable microfleece: comfy warmth without added bulk, suitable for cooler rooms.
• Secure but gentle fit: adjustable fasteners keep the sack in place while allowing natural movement.

Think practical and thoughtful: a two-way zipper opens from the bottom so you can change diapers at night without fully removing the swaddle. The sleeveless, roomy design supports natural hip movement and is recognized as hip healthy by the International Hip Dysplasia Institute.

• Two-way zipper for quiet, quick diaper changes.
• Hip-healthy design with room to move for growing hips.
• Hospital-trusted heritage: used by 1,800+ hospitals and loved by millions of parents.

In real life, HALO’s warmth and flexibility make nightly routines feel more predictable. The soft microfleece has a gentle touch against baby skin, while the adjustable wings keep baby snug without restricting growth. While every baby is unique, many families appreciate how this swaddle accommodates changing sleep needs from newborn days through early infancy.
