Cold weather riding requires a bit more strategy than suiting up for a summer jaunt along the roads, and the first layer you choose is crucial to your overall comfort. If you have to reach for knickers, tights, or thermal bib shorts before your ride, chances are good that it's cold enough outside for you to need Craft's Active Extreme 2. 0 Windstopper Boxers. For those of you who prefer to keep the chamois next to your skin on the bike, the boxers can also be used for Nordic ski cross-training. the Craft uses a stretchy, moisture-wicking fabric to construct the main body, then adds a Gore Windstopper panel to the front to strategically protect the parts you hold dear.
