Size Guide
Standard US menswear sizing — most styles run true to size.
Last updated August 6, 2026
Our range uses standard US menswear alpha sizing (S through XXXL, and XS on some styles). Most pieces are cut to a regular fit and run true to size. Where a style is deliberately oversized or slim, the product page says so under Fit.
Find your size
Measure your body, not a garment, and compare against the table below. Keep the tape snug but not tight, and measure over light clothing.
| Size | Chest (in) | Chest (cm) | Waist (in) | Waist (cm) |
|---|---|---|---|---|
| XS | 32 – 34 | 81 – 86 | 26 – 28 | 66 – 71 |
| S | 35 – 37 | 89 – 94 | 29 – 31 | 74 – 79 |
| M | 38 – 40 | 97 – 102 | 32 – 34 | 81 – 86 |
| L | 41 – 43 | 104 – 109 | 35 – 37 | 89 – 94 |
| XL | 44 – 46 | 112 – 117 | 38 – 40 | 97 – 102 |
| XXL | 47 – 49 | 119 – 124 | 41 – 43 | 104 – 109 |
| XXXL | 50 – 52 | 127 – 132 | 44 – 46 | 112 – 117 |
These are body measurements used to choose a size, not the finished dimensions of the garment.
How to measure
- Chest — around the fullest part of your chest, under the arms, tape level all the way round.
- Waist — around your natural waist, roughly level with your navel. Do not pull the tape in.
Between two sizes?
- Regular fit — take the larger size if you prefer room, the smaller if you like it close.
- Oversized fit — already cut generously; take your usual size, or size down for a less roomy look.
- Slim fit — cut closer to the body; size up if you are between sizes or prefer more room.
- Tracksuits — sized on the jacket. Take your usual top size.
