Mountain Bike Shorts

Long ago, when mountain bikers began to define their own ride style and develop equipment suited for their unique needs, they borrowed from surf and motocross apparel to create shorts that were more protective and functional than the Lycra used on road rides and by cross-country racers. These were looser-fitting than the tight bibs made of spandex and became known as baggies.

A generation later, the term no longer works. Modern mountain bike shorts have evolved into high-performance gear made for the unique challenges of riding on trails. They’re light, breathable, and fit snugly without being restrictive. This is most evident in trail shorts, which we review here.

There’re heavier, meant for more aggressive riding, but most mountain bikers will be best served by this common style. Generally, trail shorts are form-fitting to not snag on a seat. They’re constructed of lightweight, breathable material (typically nylon or polyester or a blend of similar fabrics), often coated with a durable water repellent to keep moisture from soaking through. The better ones have a secure waist snap or buckle, a pocket on the side or rear for a phone, micro waist adjustments, and effective ventilation. Many weigh less than 200 grams (about half a pound).

Mountain biking can get rowdy and the right gear will help you overcome the toughest obstacles. Mountain bike shorts are athletic cut to allow free range of movement, which is crucial when you're meeting the demands of technical trails. Features that make the ride better include moisture-wicking fabric, storage solutions and reinforced impact zones. Ride further and push harder knowing your backside is covered.


The tried-and-true rules of cycling apparel—spandex on tarmac, baggies on trail—became trends for good reason. On the road, snug, muscle-hugging bibs move with you, not against you, ensuring next-to-skin comfort as you pedal. The svelte design creates less wind resistance and improves fabric performance, so you’ll stay drier, cooler, and more comfortable. And because traditional road jerseys have back pockets there is no need for pockets on the shorts—but trends are starting to change (read on for more about our Cargo shorts).
