In the custom sock industry, material selection directly affects product performance, customer satisfaction, and brand competitiveness.
For OEM buyers and private label brands, the most common question remains:
Which material is best-cotton, bamboo, or polyester?
The answer depends on your market, product positioning, and cost strategy. This guide provides a clear comparison to help you make the right decision.
