Because Alpinestars knows that you need freedom to move while you're on the trails, it constructed the Drop Shorts with a series of stretch panels and strategically placed them on the back panel and in the crotch area. The synthetic fabric helps to pull moisture away from your skin to keep you dry. To further assist this process, zippered mesh thigh vents move air through the shorts. And because you'll spend as much time in the saddle as over it, the Drop Shorts feature a removable liner. This chamois insert is sewn from a smooth, wicking fabric that keeps you dry. Padding provides cushioning between your saddle and sit bones, hook and loop closures secure the shorts, and side pockets hold a few items while you ride.
