BUBBLE TREE Knitted Bamboo-Cotton Split-Leg Sleeping Bag

This sleeping bag incorporates original hand-drawn fairy tale scenes by artists into both the front and back panels, transforming each piece into a wearable artwork. Details like color-contrasting sleeves harmonize with the main body's pattern design, enhancing the brand's distinctive IP identity and emotional value.
Unlike traditional sleeping bags that rely on physical thickness for warmth, this model integrates Dukk® bio-based temperature-regulation technology within the fabric to maintain a stable micro-climate between 28°C and 32°C by adapting to both ambient conditions and the baby's body temperature, thus ensuring constant warmth and comfort. It introduces an intelligent temperature-sensing strip and cotton-modal one-way moisture-wicking fabric to create a temperature-humidity dual-signal feedback system. The temperature-sensing strip woven into the inner neckline visually displays perceived body temperature, while the inner cotton-modal one-way moisture-wicking fabric reveals unique brand patterns upon absorbing sweat, offering intuitive feedback on the infant's condition.
The overall cut is relaxed, with raglan sleeves and a 3D ergonomic crotch design to alleviate pressure on the shoulders and legs, guaranteeing comfort and freedom during movements like turning over and crawling. A full-length two-way zipper front and fully openable leg cuffs facilitate diaper changes at night. A widened placket and a built-in neck guard effectively prevent zipper-related pinching or skin irritation.
Regarding materials, the main body fabric consists of 66.4% regenerated cellulose fiber, while the filling contains 28.4% regenerated cellulose fiber. The base fabric is primarily made of soft and skin-friendly bamboo-cotton knitted material, the lining is a cotton-modal blend with rapid moisture absorption, and the filling combines wool and regenerated fibers, balancing warmth with sustainability.
