Fit instructions
- Use the product-specific brand chart whenever one appears in the description.
- For motorcycle jackets, measure while wearing the base or mid layer you plan to use.
- For a relaxed lifestyle fit, allow extra room at chest and waist.
- If chest and waist point to different sizes, choose the size required by the larger measurement.
Letter sizes such as S–4XL are not identical across every brand. Do not convert a letter size without checking the product chart.
