Size Guide
Getting the right fit matters — especially for flame-resistant and safety gear that needs to perform. Use the guidance below to find your size. When in doubt, size up for layering or a relaxed fit.
How to Measure
- Chest: Measure around the fullest part of your chest, keeping the tape level under your arms.
- Waist: Measure around your natural waistline, keeping the tape comfortably loose.
- Inseam: Measure from the top of your inner thigh down to the bottom of your ankle.
- Sleeve: Measure from the center of your back, across the shoulder, and down to your wrist.

Fit Tips for FR Clothing
Flame-resistant garments are designed to be worn with a slightly relaxed fit for comfort, mobility, and proper protection. Avoid a tight fit — FR clothing performs best with a small amount of air space between the fabric and your skin.
