What should I consider when customizing men's gym clothes?

 When customizing men's gym clothes, key considerations include: product type and intended use — training, running, or lifestyle; fabric selection based on performance needs; fit direction — oversized, muscle fit, or regular; color and design specifications; logo and branding method; size range and grading; target quantity and budget. Having these decisions clarified before contacting a manufacturer helps speed up the initial project review and quotation process.
