Not sure of the size?
Our size guide provides a general idea of how your body measurements correspond to our garments, however it does not fully reflect each item's unique specifications. Each piece is designed with specific fits tailored to the intended activity, taking into account ergonomics, comfort, layering systems, and optimizing the performance of fabric technologies.
NOTE: Men's fit has been updated with a revised fit. Medium size remains unchanged. Smaller sizes are now tighter and larger sizes are now looser. If your measurements are between sizes, select a larger size for a looser fit or a smaller size for a tighter fit.
How to find your measurements:
Note: Calculate your own body measurements, then select your product size.
1. Sleeve: With arm relaxed at your side and slightly bent, measure from center back neck, across shoulder to elbow and down to wrist.
2. Chest: With arms relaxed at your sides, measure under your arms, around the fullest part of your chest
3. Waist: Measure around your waist at the narrowest part.
4. Hip: Standing with feet hip width apart, measure around your hips at the widest part.
NOTE: Men's fit has been updated with a revised fit. Smaller sizes are now tighter and larger sizes are now looser.
