NIJAYS fit reference
Find your best fit
Start with your body measurements, then compare them with our US men’s size chart. All measurements are in inches unless noted.
How to measure
Measure over light clothing
Use a flexible tape and stand naturally. For shoulders and sleeves, ask someone to help.
Chest
Circle the fullest part of your chest, under the arms and across the shoulder blades.
Tip: Keep the tape level and breathe normally.
