KALA-Y Cloud Schoolbag ProMax – Wind Rider

A. 8-Dimensional Ergonomic Decompression System

The Cloud Schoolbag ProMax features a scientifically designed, 8-dimensional decompression system backed by multiple patented technologies to significantly reduce the carrying burden on children.



① Innovative Wing-Shaped Zoned Support System:

Wing-Shaped Scapula Support: Perfectly contours to the scapula, maximizing contact area to effectively disperse pressure.

Ω-Shaped Lumbar Support: Provides extensive coverage and support to the lower back, soothing spinal pressure.

Y-Shaped Airflow Channel: A 3D ventilation system that ensures breathability and prevents stuffiness.



② Detachable Mountaineering Waist Belt:

Protects the lumbar spine and offloads weight effectively, preventing the schoolbag from swaying or sagging backwards.



③ Patented U-Shaped Progressive Straps:

Engineered with a dual-core (soft & hard) layered support structure. This solves the industry dilemma of straps being "too soft to carry weight" or "too hard to fit comfortably."



④ Adaptive "Close-Fit" Shoulder Buckles:

Adjustable buckles allow for fine-tuning of the schoolbag’s center of gravity, ensuring it fits snugly against the child’s back.



 ⑤ Vertically Adjustable Sternum Strap:

Accommodates children of different heights and further aids in even weight distribution across the torso.



⑥ Diagonal Suspension Bottom Design:

Utilizes triangular mechanics for structural stability, providing effective lift to keep the bag upright and prevent bottom sagging.



⑦ & ⑧ Original Rainbow Webbing & Anti-Slip Buckles:

Rainbow Webbing: Visual guides allow for precise and symmetrical length adjustment of shoulder straps.

Anti-Slip Buckles: A locking mechanism ensures the straps remain at the desired length without sliding.



B. Patented One-Piece Fully Openable Structure

Allows the schoolbag to unzip completely flat. This makes it exceptionally easy to clean, quick to dry, and convenient to store flat to save space.



C. Premium Aesthetic & Safety Design

Signature "Academy" Style: A departure from standard schoolbag designs, offering a sophisticated, high-end academic look.

Structured Silhouette: The combination of premium fabric and leather creates a rigid, 3D shape that retains its form.

Exquisite Details: Finished with refined metal badges and relief embroidery for a touch of luxury.

360° Safety Visibility: Ensure the child's visibility and safety during night travel.
