About Louis Garneau: Louis Garneau(TM), commonly known in the world of triathlons and cycling as LG, began when Garneau started manufacturing cycling clothing in his father's garage. Having participated in bike races worldwide for over 13 years, he knew he understood the specific needs of cyclists. Soon after, Garneau put together a team of people to create comfortable and competitively priced bicycle clothing and accessories. Whether you're looking for a cycling tank, sleeveless jersey or a triathlon transition bag, Louis Garneau is an excellent choice. The expertise and work that goes in to every detail of design guarantees you're getting high-quality product that will last race after race. LG tests their apparel in wind tunnels to ensure it's as streamline as possible. By utilizing unique fabrics and technologies like Carbon-X Mesh(TM), Tritek(TM), and Aero Lazer(TM), Louis Garneau cycling and triathlon clothes wick away moisture and keep everything in its place. When you're racing, the last thing you want to worry about is your jersey, shorts or trisuit.
