About W-Number Jacket Sizing
Some denim jackets are sized using W numbers (W34, W36, W38). These numbers are based on traditional jean waist sizing and are used as a general size reference—not the actual waist measurement of the jacket.
As a rough guide:
- W34 = Small
- W36 = Medium
- W38 = Large
- W40 = XL
For the best fit, always refer to the actual garment measurements (chest, shoulders, and length) listed on each product. Denim jackets are made from rigid fabric and are often worn layered, so sizing up may provide a more comfortable fit.
