Size Guide
ALGN is designed to fit most body types. Every unit has fully adjustable straps — so if you're between sizes, you'll always get the right fit.
HOW TO MEASURE
Measure around your chest, just under your armpits. Use a soft measuring tape and keep it level all the way around.
| Size | Chest Circumference | Best For |
|---|---|---|
| S / M | 70cm – 95cm | Slim to average build |
| L / XL | 95cm – 120cm | Average to larger build |
Between sizes?
Go with the larger option. The adjustable straps let you dial in the exact fit for your body.
