Some days you need some lightweight protection. The Louis Garneau Speedzone X-Lite vest is perfect for transitional seasons, summer days that could turn rainy, or days full of climbs with chilly descents. The X-Lite 19 fabric is ultra-light weight--a size medium vest weights just 60g, and packs down incredibly small (in fact, it packs into its own collar for extra portability) so you'll barely notice it in your jersey pocket. X-Lite 19 is also wind-resistant, so it makes those fast, cold descents more comfortable. X-Lite mesh panels on the sides and back improve breathability to keep you from overheating. A rear panel cut out also makes it easy to reach into your jersey pockets to retrieve small items. A full length zip with zipper garage makes donning and removing the vest easy, while front and back reflective accents enhance visibility.
