Throwing yourself off of a bank and into god-knows-what is a good time for sure, but the bruises you get are not. The Alpinestars MTB Compression Shorts use articulated foam pads to protect your body without restricting your movement. Ventilation channels help bring in fresh air so your feet don't get funky, and the Lycra trim on your legs and thighs keep everything in place. The compression factor helps your legs recover faster without being so sore.
