How to Choose Your Size
Mongols Classic T-Shirt Sizing
The Mongols Classic T-Shirt ($24.99) is a fan favorite for good reason. Made from 100% ring-spun cotton, it's pre-shrunk and designed with a relaxed unisex fit. That means it won't shrink much after washing, and it's roomy without being baggy. To get your size, measure your chest just under your armpits, around the fullest part. Then compare to our size chart:
| Size | Chest (inches) | Length (inches) |
| S | 34-36 | 28 |
| M | 38-40 | 29 |
| L | 42-44 | 30 |
| XL | 46-48 | 31 |
| 2XL | 50-52 | 32 |
If you're between sizes, we suggest going up for a looser feel or down for a more tailored look. Many fans wear their usual size and love the relaxed fit.
Mongols Premium Hoodie Sizing
Our Mongols Premium Hoodie ($49.99) is built for comfort. It's a midweight fleece with a slightly roomy fit. The hoodie runs true to size, but if you plan to layer underneath, consider sizing up. Here's the hoodie size chart:
| Size | Chest (inches) | Length (inches) | Sleeve Length |
| S | 36-38 | 26 | 32 |
| M | 40-42 | 27 | 33 |
| L | 44-46 | 28 | 34 |
| XL | 48-50 | 29 | 35 |
| 2XL | 52-54 | 30 | 36 |
Note: The hood is double-lined and adjustable, so it'll stay put even in wind.
Other Styles: Polo and Tank Top
For a more polished look, the Mongols Polo Shirt ($34.99) is cut from cotton pique with a classic two-button placket. It fits closer to the body, so if you're between sizes on tees, go with the larger size for the polo. The Mongols Tank Top ($19.99) follows the same sizing as the Classic T-Shirt but with a narrower shoulder. Perfect for workouts or hot days.
