Around Cruiser the operative phrase for summer riding is "stay cool," and in that regard a mesh jacket can help considerably. The quality of this type of jacket has increased significantly since it first appeared on the scene, so we decided to check out some new models. First, look for a jacket that fits comfortably but not too loose. We can't recommend enough choosing a garment that has shoulder and elbow armor, too. Many jackets also include removable wind, rain or thermal liners that add some versatility.
