We've been intrigued with Louis Garneau's curious, innovative Course Superleggera Jersey since we first saw the prototype models, so when the chance to team up with LG for a Competitive Cyclist version presented itself we jumped on it faster than Voeckler on a day long, obviously doomed breakaway. The result is all the same technical features listed on the catalogue version, plus the addition of a tastefully understated Competitive logo on the chest and back. The jersey's bust is made from LG's CB Mondo fabric. Unmatched in the industry for its blend of stretchability and breathability, CB Mondo also endows the jersey with a UPFSPF 50 rating to protect from the sun. Bolstering that sun protection is the Corsa's use of Coldblack fabric treatment on darker colors, which helps reflect the sun from the material to keep you cooler for longer. Of course, the Course Super Leggera's real cooling trick lies in the shoulders, stomach, and back: the all new Kite Mesh. Kite Mesh is superlatively lightweight at just 80 grams per square meter, which contributes to the jersey's overall weight of just 90 grams. It's mesh construction allows air to pass through virtually unimpeded, and it also hastens the evaporation of moisture beyond what bare skin is capable of alone. The Course Super Leggera's construction is no less well considered, starting with what may be our favorite trend in jersey production. The arm bands don't have a cuff or a hem, they're just laser cut, flexible bands of CB Mondo that hold the jersey in place without constricting or adding any wind grabbing bumps. This stability lets the pre shaped shoulders do what they're designed to: maintain a restriction free fit across your chest and upper back while on the hoods or in the drops. The full length front zipper is hidden to reduce drag and maintain a contoured fit, and the three usual rear pockets are both angled for ease of access and supplemented by an additional, zippered media pocket for internal he...
