How to Find Your Measurements
Chest Size Measurement
- With arms relaxed at your sides, measure under your arms, around the fullest part of your chest.
Sleeve Measurement
- With arm relaxed at your side and slightly bent, measure from center back neck, across the shoulder to elbow and down to the wrist.
Note: Calculate your body measurements, then select your product size. If your measurements are between sizes, select a larger size for a looser fit or a smaller size for a tighter fit.
