Product Details
The main body of the three-dimensional canvas bag is mostly made of pure cotton canvas (usually weighing between 12 and 24 ounces, with thicker and more durable fabrics as the weight increases). Some styles may use a blend of canvas, polyester fiber, and nylon to enhance waterproofing and wrinkle resistance; The bottom and corners may be reinforced with leather or Oxford cloth to enhance durability.
Adopting the "three-dimensional cutting" process, there is a fixed support at the bottom (such as adding cardboard, EVA board or cotton pad), and the sides are stiff, forming a square or rectangular three-dimensional space, which is not easily deformed after the item is placed.
The interior usually includes one main compartment, which can be paired with 1-2 zippered inner pockets (for storing valuable items) and multiple pockets (such as pencil case, card case); External designs may include side pockets (such as water cups and umbrellas), front pockets (for tissues and keys), and some styles may have hidden anti-theft pockets on the back.
The shoulder straps are mostly wide canvas straps (3-5cm in width), adjustable in length (50-120cm), and some are equipped with pressure reducing sponge pads to alleviate shoulder pressure.
