Using a 2-Layer riptstop waterproof fabric and a fast wicking mesh liner, the Hummvee Waterproof Jacket will keep the rain out while at the same time ensuring sweat is allowed to escape, leaving you feeling dry and comfortable when riding. If you do find yourself feeling too warm then underarm zipped vents are there to help dump warm moist air and let in fresh cooling airflow. The relaxed fit makes this a jacket perfectly suited to city riding and trails, with plenty of space to layer up as well as offering you the space to maneuver over tricky trail sections and flow along city streets. As light fades you'll also find the reflective trims add a nice level of visibility, helping you to be easily seen by other road users. Part of the expanding Hummvee range this Hummvee waterproof jacket continues the fine tradition of practical and tough design that will stand the test of time.
