Alpinestars protection is sized by body measurement (not garment size). BACK protectors: by your height and waist-to-shoulder length. CHEST protectors: by your height and chest girth (separate mens and womens tables). KNEE / limb guards: by upper-leg and calf circumference. Find the section for your protector type in the chart below.
Fit: Use the section that matches your protector type. Sizes follow body measurement; some guards adjust via straps. Use as a guide only.
