Halo created the first SleepSack over 20 years ago with both safety and comfort in mind. The #1 choice of 1,700 hospitals nationwide, Halo's original wearable blanket with sleeveless design nestles baby like a soft blanket without the risk of sleep-related dangers. The signature "Back is Best" embroidery is a gentle reminder to place baby in the recommended sleep position. An inverted zipper makes for easy diaper changes. The roomy sack design allows room for kicking but cannot be kicked off, so Baby stays warm and safe all night. The SleepSack is recognized by the International Hip Dysplasia Institute as promoting healthy hip development. The original wearable blanket replaces loose blankets in the crib for a safer environment.

Made from 100% cotton interlock fabric with a TOG rating of 0.5, the SleepSack offers just the right comfort for warmer seasons or climates and can be layered with warmer sleepwear for cooler temperatures. Its double knit construction of cotton interlock fabric makes it extremely soft and a little stretchy, perfect for baby sleepwear. The inverted zipper opens from the bottom for easy diaper changes. The SleepSack is sleeveless to reduce the risk of overheating, while arm and neck openings are sized for a safer fit. It is the #1 choice of hospital nurseries to promote safe sleep.
