Every arm warmer we've ever seen and sold has certain key traits in common: They're made from Roubaix fabric for warmth; and they're lined with a thin layer of fleece to give them softness and to beef up their body heat insulation. For cool-weather riding, it's a simple-but-effective formula. But sometimes we crave a lighter weight armwarmer -- one just thick enough to disrupt the cool air from slapping our arms, but not so thick that it over-collects body heat. We're thinking temps from 55-70 degrees here, when it's not cold and frankly it's barely even cool.

The Capoforma Lycra Arm Skin is just that: Instead of Roubaix and Fleece, you get nothing but Power Lycra. It traps a fraction of the heat of beefier armwarmers, but it's warmer than naked arms alone. They're so thin, in fact, that if you're the cautious type when it comes to sun protection, you'd be comfortable in these year-round -- they're that light. The Lycra is treated with SPF 50, so you're maximizing your protection against harmful sunlight. Pick your reason: Ward off a slight chill in the early season, or ward off UV rays year-round. But the Arm Skin is an accessory just as handy as a standard set of arm warmers. They don't replace them -- they complement them.

Available in 4 colors, in two sizes: S/M and L/XL. Silicone gel grippers make them easy to customize to your arm length and girth.
