Trusted and beloved by American parents for over 25 years, HALO® has arrived in Europe. Known for their expertise in baby safe sleep, HALO® is proud to be the number one choice of over 1,700 US hospitals. HALO® SleepSack® swaddle is the only 3-way baby swaddle that adjusts to fit baby's sleep style. Swaddle with arms in, hands-to-face, or with one or both arms out to ensure baby’s best sleep. With adjustable fasteners for a perfect fit, it nestles baby like a soft blanket without the risk of sleep-related dangers—so baby can sleep both comfortably and safely.

Signature “Back is Best” embroidery is a gentle reminder to place baby in the recommended sleep position. Features an inverted zip for easy nappy changes and a roomy sack design that’s recognised by the International Hip Dysplasia Institute as promoting healthy hip development.

Safety reminder:

Discontinue swaddling when the baby shows signs of rolling over or breaking out of the swaddle wrap.
To reduce risk of fabric accidentally covering baby’s mouth or nose, swaddle must be appropriately sized, snug, positioned around baby’s torso and securely fastened.
Always place your baby on their back for sleep. And never place anything in the cot with your baby. No pillows, bumpers, toys or loose blankets.
