In terms of product design and structure, we refer to international mainstream golf equipment standards, deeply integrating functionality with ergonomics. The overall dimensions of the golf bag are strictly controlled within the internationally accepted standard of 90cm in length, 40cm in width, and 40cm in height, ensuring compatibility with the vast majority of golf carts worldwide and airline transportation requirements. For different usage scenarios, we strictly follow the QB/T 4586-2013 "Golf Bag" industry standard, categorizing products into three main types: hard-shell bags, soft-shell bags, and travel bags. The hard-shell bags use aviation-grade PC ABS composite material to create an aluminum frame structure, ensuring they do not deform or crack in temperature ranges from -20°C to 60°C; the soft-shell bags are made of 1680D high-density ballistic nylon, combined with a waterproof coating, achieving a static water pressure resistance of over 5000mm.
