Troy Lee Designs constructs the best mountain bike pants you can buy. Designed with both the seasoned and novice rider in mind, their durable, vented pants provide unprecedented protection and comfort. When you need full-leg coverage, MTB pants from TLD offer everything you've come to expect from their popular shorts just in a longer version. Specification: Single snap button-fly with 'zipper flap' keeps the zipper free from debris. Bicycle specific design in the knee results in optimal pedal performance and reduces excess material while still allowing for knee guards. More durable stretch fabric across the quads and around the rear of the pants result in a better fit and add to the durability. Rear mesh panels along the calves improve range of motion and ventilation. Tapered leg design improves pedaling and sonic welded thermo skin applied to drive side inner leg. Side waist adjusters with inset Velcro. 2 strategically placed zipper pockets. 1 upper left leg, 1 lower right side hamstring.
