HALO 100% Cotton Sleepsack Swaddle – 3-Way Adjustable TOG 1.5 (Baby Blue, Small, 3–6 Months)

Meet the HALO 100% Cotton Sleepsack Swaddle—the Original wearable blanket that replaces loose blankets in the crib, helping create a safer sleep environment. Endorsed by hospitals nationwide, it combines breathable fabric with thoughtful design to support calm, restful nights for your baby.

Soft, breathable cotton and warm, consistent comfort

The Sleepsack is crafted from 100% cotton with a double-knit construction that feels soft and gently stretchy against baby’s skin. The TOG 1.5 rating is ideal for cooler evenings in spring or fall, typically keeping the room around 68–72°F comfortable for your infant.

• Soft, breathable cotton with just enough stretch for a cozy, secure swaddle.
• TOG 1.5 warmth helps maintain a comfortable microclimate without overheating.

Three-way adjustable swaddle for growing babies

The 3-way design uses generously sized fasteners to tailor the fit: Arms-In to help reduce startle reflex, One-Arm-Out for self-soothing with a bit of freedom, or Two-Arms-Out to ease transitions as your baby grows.

• Arms-In provides a snug, secure feel during early swaddling.
• One-Arm-Out supports self-soothing while preserving most of the swaddled feel.
• Two-Arms-Out offers a clear transition path toward independent sleep.

Diaper changes without disturbance

The inverted zipper opens from the bottom for quick diaper changes without fully undoing the swaddle. Its sleeveless design minimizes overheating risk while keeping a secure fit around the neck and arms.

Size small is designed for infants 3–6 months, typically weighing 13–18 pounds and measuring 23–26 inches. Use should discontinue once your baby begins rolling over or attempts to break free.

Safe sleep with real-world use

Hospitals nationwide endorse the Sleepsack as part of a safe sleep routine, offering caregivers confidence in home use. While individual sleep outcomes vary, many families appreciate a calmer bedtime routine when swaddling is part of their nightly ritual.

In daily life, you may notice the serene blue tone creating a calm nursery aesthetic, while your baby enjoys a secure, breathable layer that moves with them as they shift positions during sleep. This Sleepsack supports a gentle transition from swaddling to a wearable blanket, helping you adapt as your baby grows and becomes more active.
