How to Measure Correctly
- Stand upright with your arms relaxed at your sides.
- Use a flexible tape measure and wrap it around the widest part of your chest (just below the armpits, across the shoulder blades).
- Keep the tape snug but not tight, and breathe naturally.
Between sizes?
If your measurement falls right between two sizes, we recommend choosing the larger size for easier adjustability and daily comfort.
