When sourcing wholesale golf bags, material selection is the foundation of product longevity. High-density synthetic leather (PU) is preferred for premium aesthetics and water resistance, while 1680D ballistic nylon offers superior tear resistance and lightweight performance. Ensure the fabric has a UV-resistant coating to prevent color fading under prolonged sun exposure. For high-end markets, verify that the zippers are YKK brand or equivalent, as zipper failure is the most common reason for product returns.
