These shirts follow a slim/standard fit frame, and are designed to fit similarly to many popular athleisure brands today. They are about 1/4th a size smaller than "true to size".
General rule of thumb is that they run slightly closer to the body than traditional shirt sizes since they're a slim/standard hybrid. If you fit in a standard size BUT BARELY, you should consider sizing up. For a more relaxed fit, you can also go one size up.
| Sizes | S | M | L | XL | 2XL | 3XL |
| Length | 29.5 | 29.75 | 30 | 30.25 | 30.5 | 30.75 |
| Chest | 36-38 | 38-40 | 40-42 | 43-45 | 46-48 | 49-51 |
| Sleeve | 24.75 | 25 | 25.25 | 25.5 | 25.75 | 26 |
| Neck | 17.5 | 18 | 18.5 | 19 | 19.5 | 20 |
If you're like us, these numbers can be confusing, so in general, here's the deal: slim fits tend to do great for lean-to-average builds, but will honestly start to show especially around the love handles as BMI goes up. You know yourself best, and should consider a more relaxed size up if you're on the fence.
Or, if still in doubt, you can always use our mantra fitting test.
Mantra fitting test
You like to say "I like fitness." = will probably fit well.
You like to say "Fitness pizza in my mouth" = might want to size up.
You like to say "I like fitness, but also fitness pizza in my mouth" = your guess is as good as ours.
Godspeed
