Our shirts tend to run pretty true to size, but we know that everyone has slightly different preferences. We always recommend that you grab your favorite shirt, measure it and compare it to our size chart.
Standard t-shirts have a more relaxed fit. They are available from S to 6XL (including a tall option up to 4XLT). We also offer Women's T-Shirts (which actually fit like Women's T-Shirts and not shirts made for ants) with sizing available from S to 4XL.
Premium shirts have a more fitted style. They are a lightweight, ringspun cotton available in sizes S to 3XL. Men's Premium sizing is similar to standard shirts. However, the Women's Premium shirts are much different than our standard sizing. They are more akin to Juniors sizing.
Again, we always recommend grabbing your favorite shirt for reference.
