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

Safe, Snug Sleep Starts Here

The HALO Micro-Fleece Sleepsack Swaddle blends hospital-trusted craftsmanship with plush, gentle warmth. With a TOG 3.0 rating, it provides cozy coverage in cooler nurseries (61–64 °F) without the need for loose blankets. This is the Small size, ideal for infants around 3–6 months, offering a secure cocoons-place for restful nights while your baby grows and explores new sleep patterns.

Designed as a versatile 3-in-1 swaddle, it adapts as your baby develops: arms can stay in for a snug, womb-like feel, hands-to-face for self-soothing, or arms-out when your little one starts to roll or stretch more. The architecture emphasizes a secure fit, yet remains forgiving enough to accommodate gentle movement and growth.

• Three-way adjustable wings tailor the swaddle to baby’s preferred sleep style and growth stage.
• Secure fasteners maintain a snug feel without restricting hip movement or natural leg motion.
• Two-way zipper enables night-time diaper changes without fully removing the swaddle, keeping baby cozy.

Hip Healthy, Baby-Friendly Design

The sleeveless, roomy sack supports natural hip development and is recognized as “Hip Healthy” by the International Hip Dysplasia Institute. This design helps keep little legs in a natural position, reducing the risk of constriction while sleeping.

• Hip-friendly construction supports comfortable, healthy hip flexion during sleep.
• Secure, snug layering minimizes the need for loose blankets in the crib.

Real-Life Comfort You Can Feel

Parents notice the soft, cloudlike touch of micro-fleece against delicate skin, paired with warmth that makes cooler nights feel reassuringly calm. The fabric resists overheating when paired with the right room temperature, creating a balanced sleep environment without excess bulk.

Care is simple: per the fabric guidelines, you can wash cold and tumble dry low. Always place baby on their back to sleep, following safe sleep practices.

A Little Magic in Everyday Moments

Our Hedwig design adds a playful, personal touch to the classic SleepSack experience, turning nighttime into a small, comforting ritual for both baby and caregiver—without compromising warmth, fit, or safety.
