HALO Micro-Fleece Sleepsack Swaddle – 3-Way Adjustable, TOG 3.0, Hip Healthy (Grey Stars, Small, 3–6M)

Soft, secure warmth for nursery routines

The HALO Micro-Fleece Sleepsack Swaddle is the original SleepSack Swaddle, trusted by hospitals and millions of families for calmer nights and a safer sleep routine. Its familiarity and proven design have helped many caregivers feel confident during early months.

Built for cool nurseries, the microfleece offers a cozy, snug feel with a TOG 3.0 rating. When your room sits around 61–64 °F (16–18 °C), this wrap helps maintain a comfortable microclimate without extra layers, creating a warm, breathable sleeping environment.

Versatile, baby-centered swaddling

The 3-way adjustable wings adapt as your baby grows and as sleep preferences change. Try arms-in for a secure start, hands-to-face for soothing touch, or arms-out for a looser feel during milestone moments.

• Arms-in for snug, secure sleep transitions
• Hands-to-face comfort when babies seek soothing touch
• Arms-out option to encourage independent movement

Smart design for night-time routines

The two-way zipper opens from the bottom, enabling quick diaper changes without fully removing the swaddle. This simple detail can support calmer night-time routines for both baby and caregiver.

• Bottom-access zipper for fast diaper changes
• Safe, roomy design to support natural hip movement

Hip-healthy and development-friendly

Recognized as Hip Healthy by the International Hip Dysplasia Institute, the HALO SleepSack Swaddle features a sleeveless, roomy silhouette that supports natural movement while helping maintain a cozy, secure vibe.
