A light but resilient wind jacket like the Louis Garneau Men's X Lite jacket is arguably the most useful top you can own. It can be a light layer for windy or only slightly chilly days. It can be an element proof outer layer over a thicker jacket or long sleeve jersey when the temperature drops or the rain approaches. And, since it's easily packable, it's easy to pull off and stuff into a jersey pocket when it's no longer needed. It's a smart piece, and it's worth every penny. The X Lite's construction is simple and effective, using two fabrics from LG's X Lite family. X Lite 19 is the business end of the jacket. It's wind resistant, has a high denier for durability, and still manages to breathe well so your wind free microclimate doesn't turn clammy and damp after 30 minutes in the saddle. X Lite Mesh is a lightweight mesh designed for one thing: comfort. Well, and stretch. And breathability. OK, so it does lots of things, all of which make it the material you want for optimal ventilation, which is why LG uses panels of it for the X Lite Jacket's underarms. The jacket is cut according to LG's pro fit, which means it's snug enough for racing and there's no extra material to flap in the wind that it's designed to block. The articulated elbows and stretch trim at the collar, wrists and hem mean you'll be able to move freely in the saddle including reaching into jersey pockets through the rear access back opening without compromising comfort. The full length zipper has a neck garage to eliminate chafing, a full length flap, and reflective accents. The chest and upper back have yet more reflective elements to help keep you visible in low light conditions. The Louis Garneau X Lite Men's Jacket is available in six sizes, ranging from X Small to XX Large, and in the colors Blackred, Orange Fluo, and Whiteblack.
