Size & Fit Guide

Start with the quick estimate below using your height and weight. Chest measurement is what actually determines fit — if it points to a different size than your height/weight, go with your chest measurement.

Between sizes?

  • Prefer a fitted look → size down
  • Prefer comfort, layering (hoodie/sweatshirt underneath), or a roomier feel → size up
  • Leather and denim styles don’t stretch — if you're between sizes in one of these, size up

How to Measure

Chest

  • Stand straight with arms relaxed at your sides.
  • Wrap a tape measure around the fullest part of your chest, leaving about 1 inch of extra space.
  • Leather/Denim Jackets: these fabrics do not stretch. For 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.

FAQs

Most sizing questions come down to one thing: are you between two sizes? If so, size up for comfort or layering, size down for a closer fit. Leather and denim styles don't stretch — size up if you want more room. Still unsure? Email support@innocentarmor.com with your height and weight.
