How to Measure
Chest
- Stand straight with arms relaxed at your sides.
- Wrap a tape measure around the fullest part of your chest.
- Keep the tape comfortably snug — leave about 1 inch of extra space.
- Leather/Denim Jackets: These fabrics do not stretch. If you prefer a more relaxed fit, choose the next size up.
Sleeve
- Start at the center of the back of your neck.
-
Run the tape over your shoulder and down your arm to your wrist.
Waist
- Measure around your natural waistline using the same method as the chest.
- Keep the tape snug, but not tight.
Between Sizes?
If you’re between sizes, we recommend selecting the larger size for a more comfortable fit.
