HALO 100% Cotton Sleepsack Swaddle for Newborns – 3-Way Adjustable, TOG 1.5, Baby Blue

The HALO 100% Cotton Sleepsack Swaddle is designed to replace loose blankets in the crib, creating a safer sleep space for your newborn. The soft, breathable fabric and thoughtful design are meant to support calm nights and easier swaddling during the early weeks. In this Baby Blue version, the newborn-friendly fit is tailored for 0-3 months, 6-12 lbs, and 19-23 inches.

Fabric and warmth matter. This sleep sack is crafted from 100% cotton with a double-knit construction that feels gently stretchy, giving a snug, cozy embrace without added bulk. The TOG 1.5 rating, suitable for a room temperature of 68°-72°F, makes it a solid choice for cooler spring and fall evenings when parents want a little extra warmth without overheating.

Versatility at its core. The 3-Way Adjustable Swaddle Design uses generously sized fasteners so you can tailor the fit as your baby grows. Choose Arms-In to help reduce startle reflex, One-Arm-Out for familiar self-soothing, or Two-Arms-Out as your little one begins a transition toward a traditional sleep sack.

Practical design for busy nights. An inverted zipper opens from the bottom for easy diaper changes without disturbing the swaddle. The sleeveless cut minimizes overheating risk, while snug arm and neck openings keep the baby feeling secure through the night.

Sized for newborns and built with safety in mind. This sleepsack is ideal for babies measuring 19-23 inches and weighing 6-12 pounds. Discontinue use when your child begins to roll over or attempts to break free from the swaddle.

What you may notice as you use it. A safer sleep space, added convenience for diaper changes, and a gentle transition path toward independent sleep. Hospital endorsements further reflect the product’s trusted design, offering reassurance for caregivers seeking a time-tested sleep solution without relying on blankets.
