Why do mountain bikers wear baggy shorts?
Wearing baggy shorts is a mountain biker's way of protecting themselves from scrapes and cuts. The extra layer of material helps to cushion falls, and the loose fit allows for a full range of motion when pedaling.
Baggy shorts provide plenty of storage space for tools and snacks. Most styles have multiple pockets and loops or clips for attaching additional gear. And since they are made from durable fabrics, baggy shorts can withstand the rigors of off-road riding.
