The sky is dark, those clouds in the distance look menacing, and the wind gusts are nothing short of icy. But you've got all afternoon, so against everyone else's better judgment, you're going out there for a ride, anyway. If you're in the habit of heading out on days like this, we'd recommend having Castelli's Foul Weather Cream on hand. When you apply the cream directly to skin, it acts as a shield against water, wind, and cold temperatures, convincing your muscles that they're being asked to labor in much less taxing conditions. Minimalists rejoice -- by applying it directly to your skin, the Foul Weather Cream eliminates the need to wear layers of bulky clothing to stay warm. If you're concerned about what types of chemicals Castelli uses to achieve this effect, rest assured that the formula does not contain petroleum, and that plant-based ingredients make up 57% of its composition.
