Even downhillers have to pedal from time to time, so Alpinestars designed the gravity-loving Manual Short with lightweight fabric and plenty of venting to keep you cool when you have to hit some hills or do some hike-a-biking. A blend of polyester, spandex, and mesh provides toughness, stretch, and air movement right where you need it, and additional thigh vents help you stay cool even if you're padded up under the hot sun. The hook-and-loop waist adjustment system lets you dial in a fit that won't slip or squeeze, and the relaxed fit easily accommodates pads and boosts your steeze factor. Alpinestars included a removable mesh liner complete with a moisture-wicking and flexible chamois, to keep your undercarriage safe and comfortable when you're ripping around fast berms and through techy sections of trail. There are also plenty of pockets, including a zippered media pocket, to keep your snacks, tools, and tunes close by and easily accessible.
