HALO SleepSack Swaddles

The HALO SleepSack Swaddle was designed around one goal that keeps new parents up at night: helping babies sleep safely on their backs, without loose blankets in the crib. Instead of a traditional blanket wrap that can come undone, the SleepSack is a wearable blanket with an adjustable swaddle wing system, so your newborn stays snug, warm, and secure through the night.

What makes these particular swaddles worth reaching for is the 3-way adjustable design. You can swaddle arms in for the youngest newborns who startle easily, swaddle arms out once your baby starts showing signs of rolling, or use the wings folded down as a plain sleep sack. That flexibility means the same garment adapts as your baby grows and their sleep habits change.

All the swaddles in this collection are made from 100% cotton in a 1.5 TOG weight — a middle-of-the-road warmth rating suited to typical room temperatures around 68–72°F. Cotton breathes well and is gentle against newborn skin, which matters for the many hours a day an infant spends sleeping. Sizing is simple and based on weight and age: the Newborn (0–3 Months) size fits the earliest weeks, while the Small (3–6 Months) size carries your baby through the next stage.

Colors and prints range from the neutral Heather Gray to the cheerful Sunshine Rainbows, woodland-themed Forest Friends, and calming Midnight Moons Gray — so you can pick something that suits the nursery or makes a practical, welcome baby-shower gift.

A quick note on safe use: the SleepSack should fit snugly around the chest but leave room for the hips and legs to move freely, and swaddling arms in should stop once your baby shows any sign of rolling over. Follow the age and weight guidance on each product for the right fit.
