For team or retail orders, suppliers should offer Hydro-dipping or professional-grade spray painting for shell colors, and 3D precision-cut vinyl decals for logos. Ensure the supplier can provide custom-fit padding systems and various facemask configurations (e.g., QB, Lineman, or Skill Position styles). High-end manufacturers on Made-in-China.com often provide OEM/ODM services where you can specify the thickness of the internal liners and the type of chin strap buckle (e.g., hard cup vs. soft cup).
