HALO 100% Cotton Sleepsack Swaddle – 3-Way Adjustable, TOG 1.5, Newborn 0-3 Months

Safe, breathable sleep for newborns

The HALO 100% Cotton Sleepsack Swaddle is designed to replace loose blankets in the crib, offering a cozy wearable alternative that promotes a calm sleep environment. This version combines soft fabric, thoughtful design, and trusted branding to help parents feel prepared for nights that feel a little easier. Endorsed by hospitals nationwide, it stands as a practical option for caregivers seeking a cozy, secure layer for their newborn.

Soft, breathable materials and ideal warmth

Made from 100% cotton with a double-knit construction, the fabric delivers a gentle, slightly stretchy touch that stays comfortable against delicate baby skin. The TOG rating of 1.5 is suitable for room temperatures around 68°–72°F, making it a good choice for cooler evenings in spring and fall. The sleeveless design reduces overheating risks while preserving a secure fit around the neck and arms.

• 100% cotton with durable double-knit construction for a soft, breathable feel
• TOG 1.5 rating aligns with cooler room temperatures
• Sleeveless cut minimizes heat buildup while keeping openings snug

Three-way adjustability for growing babies

The design offers three fit modes to adapt as your baby grows and sleep preferences change. Use Arms-In to help reduce startle reflex, One-Arm-Out for self-soothing with a familiar hand position, or Two-Arms-Out to transition toward a wearable blanket as swaddling ends. Generous fasteners ensure a personalized, secure fit without sacrificing comfort.

• Arms-In for a snug feel and secure wrap
• One-Arm-Out to support gentle self-soothing
• Two-Arms-Out to ease transition away from swaddling

Convenient design for quick changes

A thoughtfully inverted zipper opens from the bottom to simplify diaper changes without fully disturbing the swaddle. The sleeveless silhouette and secure arm openings help maintain a comfortable, safe fit while you tend to essential night-time needs.

• Bottom zipper for easy diaper changes without waking baby
• Secure neck and arm openings to minimize movement
• Easy to put on and remove, supporting busy parents

Size, care, and usage reminders

This product is sized for newborns weighing 6–12 pounds and measuring 19–23 inches. Discontinue use when your baby begins rolling over or attempting to escape the swaddle. For best results, follow the 0–3 month guidelines and monitor your baby’s comfort and temperature regularly.

While the HALO Sleepsack Swaddle can help support safe sleep routines and a cozy nighttime routine, it does not guarantee specific outcomes. Use as part of your overall baby care plan and adjust based on your child’s cues.
