You spend giant wads of cash trying to drop weight on your bike. Why would you spend even more on a pair of full featured shorts with a bunch of stuff you don't need. Heavy fabric and zippered vents add weight. The Alpinestars Rover Short is made with an extremely lightweight but durable polyester fabric that breathes well and wicks moisture away from your skin. As far as features, the Rover has things you need like a removable liner short with chamois and ignores the things you don't like a built in HD video camera.Alpinestars built the Rover Shorts with strategically located stretch panels. A stretch poly rear yoke provides an unlimited range of motion. This also adds to the shorts' durability, because it stretches rather than tearing. The synthetic fabric pulls moisture away from your body to keep you dry and comfortable, even in the heat of the summer. Double seam reinforcements provide bulletproof durability, and the seamless seat area increases comfort and eliminates chafing. An EVO removable liner with a chamois absorbs shock and vibration to reduce fatigue. It also manages moisture to keep you dry and comfortable. The liner can also be worn with other shorts, so you can transform any of your other shorts into bike shorts. Alpinestars also included a double snap fly and belt loops to let you perfectly dial your fit. Two cargo pockets and two deep front pockets provide comfortable, convenient, secure storage while you ride.
