Size Guide
Last updated: 28 September 2026
Measurements for our jackets, plus the sizes of the grid, pins and patches. All garment measurements are taken with the garment laid flat and may vary by up to 2 cm.
Grid Work Jackets
All six jacket styles share one relaxed-fit size chart. Chest is measured across the front from armpit to armpit and doubled; length is measured at the back from the base of the collar to the hem.
| Size | Chest | Length |
|---|---|---|
| S | 106 cm / 42 in | 70 cm / 27.5 in |
| M | 112 cm / 44 in | 72 cm / 28.5 in |
| L | 118 cm / 46.5 in | 74 cm / 29 in |
| XL | 124 cm / 49 in | 76 cm / 30 in |
How to choose
- Lay a jacket you like flat and measure across the chest from armpit to armpit. Double it.
- Pick the size whose chest measurement is closest. Between sizes? Choose the larger one if you want to layer a hoodie underneath.
Caps
All caps and the beanie are one size. Caps have an adjustable back; the beanie has a deep turn-up cuff.
