Alpinestars Hyperlight Jersey - Short-Sleeve - Men's - $71.95

Four miles into a brutal, sun-baked, five-mile climb, any little thing can add to the agony. Cresting a false summit into a surprise headwind can just about break your spirit. That's where aerodynamics come into play, and that stylish, loose freeride jersey, while it looks cool, is your enemy. Serious XC riding (that's uphill AND downhill) calls for something that wears a little bit less like a sail, like the Alpinestars Hyperlight Jersey. The Hyperlight isn't as snug as a road jersey, but it helps with aerodynamics enough to alleviate some of the pain of a headwind. The Hyperlight Jersey was designed to take the edge off the hottest summer days. The ultralight polyester fabric pulls moisture away from your body to keep you dry and comfortable, even in the heat of the summer. Alpinestars also designed the Hyperlight Jersey with cooling mesh panels that push hot, stale air out and allow fresh, cool air to flow in and around your torso, and a half-zip front that allows you to dump heat quickly. The Hyperlight's elongated lower back profile protects you from the sun and prevents unwelcome exposure. Pull-cord-equipped zippers make it easy to make adjustments quickly, even in gloves. There's also a flat rear pocket for tools and snacks and a separate compartment for your phone or MP3 player with an internal headphone cord conduit, The Alpinestars Hyperlight Short-Sleeve Jersey comes in Black, Light Grey, Lime Green, and Royal Blue and is available in sizes Small to XX-Large. - $71.95
