However, because of its heft, the FXRG Nylon is more a winter, spring and fall jacket. Using it on hot days would be pushing it, especially if you ride with a windshield. An integrated but removable perforated kidney belt added comfort on long trips. Nice touch, Harley.

Two slash pockets up front give you basic storage, while an inside pocket system provides a stash for your cell phone, sunglasses and, other small items.
