WAA is a European brand known for its very slim fit, which differs from North American sizing standards. We strongly recommend consulting the provided WAA sizing guide. As a general rule, choose at least one size up from what the guide suggests. If you are at the upper end of a size range, consider going up two sizes.

The Trail Runner Store does not assume responsibility if the sizing is still not a perfect fit for you.

Even lighter than the outer short of the Ultrashort 3-in-1, it was developed in the desert and is optimal for temperatures above 40°C.

The shorts are so light and breathable, you'll forget you have them on.
