For the rugged off-roader and those who ride in cold weather, Leatt has a range of jackets. Beginning with its heaviest-duty item, the GPX 5.5 Enduro is constructed with a water-resistant shell, strategic stretch panels, removable sleeves, a rear storage pocket, and an internal hydration system that holds a 3-liter water bladder. The GPX 4.5 X-Flow shares similar features to the GPX 5.5 Enduro, but with a more minimalistic design. It uses a ventilated X-Flow shell, removable sleeves, a rear storage pocket, and an internal hydration system. Finally, for the single-track woods rider or GNCC racer, the GPX 4.5 Lite was developed with a lightweight, water-resistant, flexible soft shell with removable sleeves and a rear storage pocket.
