Mountain Biking Bib Shorts ST 900

Do you wear them with or without underwear?

And yes, undershorts are worn without underwear.



With underwear, you are more subject to chafing and shearing... All combined with perspiration (heat + humidity): this is quite the recipe for infections.

What is a "mesh" fabric?

Mesh fabric is thinner, lighter, and airier than cotton or polyester fabric. This breathable fabric wicks away perspiration more quickly. The fabric doesn't leave a damp feeling on your skin (which can give you chills while cycling), making the bib shorts more comfortable to wear (feels like a "second skin").
