Carany Cloud 3.0 Ergonomic School Backpack – 20L Anti-Sagging Design for Grades 3-6

Give your student the ultimate support they need for the busy school year with the Carany Cloud 3.0. Specifically engineered for children in grades 3 through 6, this 20L high-capacity backpack (Model CX2717) combines advanced spinal protection with a lightweight, "cloud-like" feel. Designed to combat the heavy loads of modern textbooks, the Cloud 3.0 features a revolutionary anti-sagging system that promotes a tall, healthy posture while ensuring all-day comfort.

Key Benefits

Advanced 6-Dimensional Anti-Sagging System:** This comprehensive support network includes O-shaped ergonomic shoulder straps and a Y-shaped breathable back panel. Together with the adjustable chest buckle and cable-stayed support base, it keeps the weight close to the body and prevents the bag from drooping, significantly reducing the strain on the spine.

Patented Easy-Clean Structure:** Featuring a unique integrated openable design (Patent No. ZL 202121101660.0), the backpack can be fully unzipped and laid flat. This makes deep cleaning effortless and allows for space-saving storage when not in use.

99% Antibacterial Protection:** The interior is lined with a specialized double-layered antibacterial fabric that boasts a 99% inhibition rate against common bacteria like E. coli and Staphylococcus aureus, ensuring a more hygienic environment for school supplies.

Smart Scientific Partitioning:** With a spacious 20L capacity, the bag includes a dedicated internal divider to keep books upright and stable. Multiple front pockets and elastic side pockets provide quick access to water bottles, umbrellas, and small essentials.

All-Weather Durability & Safety:** Crafted from high-density, water-repellent fabric, this bag is built to withstand wear, tear, and unexpected rain. For low-light commutes, 360° reflective warning strips provide high visibility to ensure your child’s safety.

Key Specs

Model:** CX2717

Capacity:** 20L

Target Group:** Elementary students (Grades 3–6)

Material:** High-density water-repellent fabric

How to Use

To maximize the ergonomic benefits, place the heaviest textbooks in the main compartment against the internal divider; this keeps the center of gravity close to the back to minimize swaying. Use the "rainbow scale webbing" to ensure both shoulder straps are adjusted to the same length. Fasten the adjustable chest buckle to distribute weight evenly across the torso. The elastic side pockets are ideal for securing water bottles and umbrellas to prevent them from falling out during movement.

Care & Safety

The high-density exterior is designed to be dirt-resistant and easy to wipe down. For a thorough cleaning, utilize the patented integrated structure to unzip the bag completely. Avoid using harsh chemical bleaches that may damage the water-repellent coating or the antibacterial properties of the lining. Ensure the 360° reflective strips are kept clean to maintain maximum visibility during evening or early morning walks.

Notes

"Six-dimensional anti-sagging design" helps maintain a healthy, upright posture for growing children.
