Padded liner shorts, also known as a chamois (pronounced: chammy), are used by many, but certainly not all, riders to enhance comfort while riding. Comprised of a tight-fitting spandex or mesh material with a chamois pad for your underside, they create a cushioned surface between your sit bones and your bike saddle. When used with baggy mountain bike shorts, these thin liners are simply worn underneath. All of the shorts we tested for this buyer’s guide are sold without a padded liner short, although several can also be purchased with one for an additional fee. While an included liner short can add value to a purchase, they are typically not the highest quality, in our experience. In general, we have found that it’s best to spend a little more on a higher-quality padded liner short for maximum comfort. This ensures that you can get one that fits properly and provides the desired level of cushioning.
