The Alpinestars Fluid Agent MX pants are designed for all forms of off-road riding, made from highly durable 600D poly-fabric with PU coating, stretch corduroy insert panels, synthetic leather reinforced inner-leg panels and a technical yarn for added durability and heat resistance. Stretch fabric panels in critical areas give movement, and the ergonomic pre-curved leg offers exceptional comfort in the riding position. A mesh lining offers breathability and keeps you fresh. The ratchet closure at the waist provides a secure and variable fit for the perfect sizing. A zipped fly gives ease of use.
