Sizing is generous and this is already designed to fit loose. Please do not size up!

Please utilize the WAIR Recommended Size tool via the product page below the size dropdown. WAIR uses AI from six simple questions to recommend your size. AI detects size and fit differences at a product level to help each customer purchase the best fitting product.

We have designed each product to fit the way it should, relative to your size. For example, if you are a size large, you will likely wear a large across our entire product lineup and each product will fit the way it's intended. Tees and sweatshirts provide a looser fit, while polos and jerseys often are more tailored, while still providing plenty of room to move. If you're in-between sizes, we recommend you choose the smaller of the two sizes. When in doubt, please refer to your WAIR Recommended Size.
