Founded in 1963, Alpinestars developed the first motocross boot in 1965. Development continued at pace, with the company producing boots for all forms of motorcycling, road and off-road, competitive use and leisure; they then graduated to all clothing, too and continue to this day, to be at the forefront of motocross clothing technology and development. The Alpinestars Racer Tactical MX jersey is made from an advanced stretch poly-fabric construction that is lightweight, moisture-wicking and incorporates stretch material in key areas. Designed for the rigours of off-road riding, it offers an ergonomic design with pre-curved sleeves and a longer rear with breathable stretch and mesh inserts for outstanding freedom of movement and airflow for maximum riding comfort. A more open, relaxed fit collar offers superior comfort and fade-resistant graphics. The matching pants are made from durable poly-fabric/nylon construction that is PU coated for additional strength and durability. Large rear stretch panel inserts provide increased comfort and flexibility to the waist and lower back with lightweight and ventilated mesh with stretch panel inserts for an improved fit and excellent freedom of movement. Heavy poly-fabric reinforcement on the seating area and inner leg panels provide superior abrasion resistance, and leather-reinforced inner-leg panels for heat resistance, grip and durability. Pre-curved ergonomic legs give superior comfort in the riding position, and innovative 3D knee construction and hidden expansion panels accommodate knee protectors. A convenient interior hip pocket allows storage for keys/coins, and a ratchet closure with dual waist adjustment gives a secure and custom fit.
