Find the right size
Our tees come in S through 3XL. The fastest way to get the fit right is to measure a shirt you already own and like, then match it to the chart below.
Size chart
All measurements are taken with the shirt lying flat. Measurements can vary slightly from shirt to shirt.
| Size | Body width (armpit to armpit) | Body length (shoulder to hem) |
|---|---|---|
| S | 18 in / 45.5 cm | 28 in / 71 cm |
| M | 20 in / 51 cm | 29 in / 73.5 cm |
| L | 22 in / 56 cm | 30 in / 76 cm |
| XL | 24 in / 61 cm | 31 in / 78.5 cm |
| 2XL | 26 in / 66 cm | 32 in / 81.5 cm |
| 3XL | 28 in / 71 cm | 33 in / 84 cm |
How to measure
- Pick the T-shirt you reach for most — the one that fits the way you like.
- Lay it flat on a table or bed, front side up. Smooth out the wrinkles.
- Body width: measure straight across the chest, from the seam under one armpit to the seam under the other.
- Body length: measure from the highest point of the shoulder, right next to the collar, straight down to the bottom hem.
- Compare both numbers with the chart. Width matters most for comfort; length decides how far it hangs below the belt.
Fit tips
- Classic fit. Our tees are cut in a classic, regular fit — not slim, not oversized.
- Like a roomier shirt? Go up one size.
- Stuck between two sizes? Choose the larger one.
- Wearing it over a layer or under a riding jacket? Check the width number against the shirt you'd normally wear that way.
Buying as a gift?
Borrow a shirt from his drawer for five minutes and measure it. If that's not possible, choose the size he usually buys in a regular-fit tee, and when in doubt, go one size up.
