Assos' Trail collection blends the boundaries between comfort and support. Specifically for its mountain bike short counterpart, the Trail Liner Shorts is what we're looking for when we need increased breathability and cushioning on trail. With its OFFROAD insert and 10-millimeters of memory foam, the Trail Liner Shorts are set to take us up trail and back down again. This first layer offers impact protection and all the support we'll need while we're riding.
