Body measurements. Measure your body, not the garment. Use all measurements from the table.
| Size | Chest (cm) | Waist (cm) |
|---|---|---|
| S | 96–99 | 93–97 |
| M | 100–103 | 98–101 |
| L | 104–107 | 102–105 |
| XL | 108–111 | 106–109 |
| XXL | 112–115 | 110–113 |
How to measure
Chest: measure around the widest part of your chest. Keep the tape measure horizontal.
Waist: measure around the narrowest part of your waist.
The tape measure should fit snugly but not be tight. If you fall between two sizes or outside the table, please ask us for advice.
