usbettas Baby Sleep Sack 3–6 Months – Cotton Sleep Sack with Detachable Sleeves, 1.0 TOG, 2-Way Zipper (Ocean)

Soft, breathable cotton for calm nights

The usbettas Baby Sleep Sack is designed for 3 to 6 month olds, using premium 40S cotton that feels gentle on delicate skin. Its breathable fabric helps baby stay comfortable as room temperatures shift, making it suitable for air conditioned spaces or homes that experience changing climates.

Seasonal versatility you can trust

Detachable long sleeves offer all-season flexibility. Keep sleeves on for cooler evenings and sleep through the night, or remove them for warmer days or active daytime play. This makes the sleep sack a practical option for daycare naps, fall and winter nights, and homes with cooling systems.

Lightweight warmth for easier nights

With a lightweight 1.0 TOG, the sleep sack provides gentle warmth without bulk. It helps prevent loose blankets while keeping baby comfortable, whether at home or away, so you can feel confident about overnight coverage in cooler environments.

Designed for easy nighttime changes

The two-way zipper enables quick diaper changes without fully undressing your baby. A zipper guard protects tender skin and keeps nighttime changes quiet and smooth, reducing disturbance during late hours.

Smart comfort monitoring on the go

A built-in chest temperature strip helps you quickly gauge skin-temperature and adjust layers without waking baby. The fabric is machine washable, making everyday care straightforward for busy families.
