The fit of the Louis Garneau Course Mitts is designed to eliminate sources of chafing and is tailored to fit like a second-skin. This is achieved by a series of truly innovative methods. Louis Garneau's patented progressive padding allows for maximal shock protection and absorption: 4mm padding on the ulnar nerve, 3mm padding at the metacarpus regions, and 2mm on the median nerve. Using their unique and patent-pending moulding process, this padding is seamlessly integrated to the palm for a incomparable handlebar feel. The outer palm is made of Clarino Synthetic Leather, a super soft yet durable material for a maximum comfort and breathability. Through a precision cut, laser cut fingers eliminate stitching or hems at the finger openings without fraying. Patent-pending finger-puller tabs at the fingers make the gloves easy to remove even with perspiration and silicone-coated segments increase grip and stability. A seamless one-piece upper hand is made of Speedtech fabric. The edge of the wrist has also been fused, not stitched, to allow a perfect air flow from the upper-hand to the arm. Treated with coldblack, the fabric reflects heat and the fabric stays cool to the touch. The proprietary and patented Ergo Air System adds ventilation at the palms allowing air to circulate to skin of the hand, reduce moisture build-up, and stabilize hand temperature even when the hand is on the handlebar.
