Cozy, Safe Sleep for Your Newborn

The HALO Micro-Fleece Sleepsack Swaddle has a long-standing hospital trust behind it. The original SleepSack Swaddle is used by more than 1,800 hospitals and trusted by millions of parents for safer, sounder nights. Crafted from soft micro-fleece and rated TOG 3.0, it provides warm comfort in cooler nurseries (61–64 °F) without the bulk of loose blankets, helping parents feel confident as they settle their baby for rest.

Three-Way Adjustability for Growing Sleep Styles

As babies grow, sleep preferences can shift. This swaddle uses flexible wings that let you wrap arms in, tuck hands-to-face, or leave arms out. The secure fit remains stable while your baby transitions through different sleep needs, giving you flexibility without rewrapping.

• Arms-in swaddle for calming initial sleep
• Hands-to-face option to encourage self-soothing
• Arms-out mode as baby grows

Warmth Without Overheating

Designed for cool-room nights, the plush microfleece feels soft against delicate skin. With TOG 3.0 warmth, it provides snug heat in chilly nurseries, helping maintain a comfortable sleep temperature without extra layering.

Hip Healthy, Roomy Design

The sleeveless, roomy sack allows natural hip movement and leg positioning, supporting healthy development as babies move during sleep. HALO SleepSack Swaddle is recognized as Hip Healthy by the International Hip Dysplasia Institute.

Practical Details for Nighttime Routines

A two-way zipper opens from the bottom for quick, quiet diaper changes without fully removing the swaddle. Strong adjustable fasteners ensure a secure fit at every stage, reducing disruption during late-night care.
