Designed from the inside out for speed, the Fox's Livewire shorts have all the aerodynamic performance of a Lycra bike short with the look and feel of traditional mountain biking shorts. The result is a pair of shorts that looks as good off the bike as it feels on it. Constructed from a structured poly/spandex blend with 4-way stretch, these shorts feature Fox's fit-lock "Wi-Fly" zipper-less fly system that absolutely will not come loose while you ride. The Velcro adjustable waist ensures you get just the right fit for your form. The removable liner comes with the Evo chamois, which features a breathable mesh lining and laser cut elastic leg grippers to keep you comfortable and supported.
