You need a mountain bike short with all the essentials -built-in chamois, pockets for whatever you need to bring along, and adjustability for a solid fit. We took care of all of that with the Squad Short, a no-nonsense MTB short with an snap-attached liner that is removable, should you need. The point of this short? Stop trying to decide what to put on and just get out there and ride. Flylow Squad Shorts w/ Liner Mens | Black | 32 | Christy Sports
