USBettas Baby Sleep Sack 3–6 Months | Cotton Sleep Sack with Detachable Sleeves, 1.0 TOG, 2-Way Zipper, Temperature Strip

Introducing the USBettas Baby Sleep Sack for ages 3–6 months, a breathable cotton wearable blanket designed for gentle warmth and easy night-time routines. Crafted from premium 40S cotton, this soft fabric rests softly against delicate baby skin while helping maintain a comfortable microclimate through the night. The lightweight 1.0 TOG provides just-right warmth for cool rooms or air-conditioned homes, letting you move through seasons with fewer wardrobe changes.

All-season comfort with detachable sleeves

The detachable long sleeves let you tailor warmth to the moment—remove them on warmer days or during active play, then reattach as the evening cools. This smart design supports daycare naps, travel, and homes that experience quick temperature shifts. With sleeves on, your little one stays snug during cooler evenings; with sleeves off, they enjoy a lighter feel during daytime activities.

The two-way zipper is thoughtfully designed with a guard to protect delicate skin and keep nighttime changes quiet. With the added temperature strip, parents can gauge warmth at a glance and adjust layers without waking their child, supporting a calm, predictable bedtime routine.

Practical design for busy nights

As a wearable blanket, the sleep sack eliminates loose blankets while providing comfortable freedom of movement. The soft cotton stays breathable enough to help prevent overheating, and the lightweight construction keeps baby cozy without bulk. Parents can rely on easy care and dependable daily use.
