Firstgear Adventure Mesh Jacket Review http://www.revzilla.com/motorcycle/fi... New for this year, the Firstgear Adventure Mesh Jacket is a ¾ length warm weather jacket. Made predominantly of mesh, this jacket will see you through the hot days of summer, and a removable windproof, water-resistant liner extends the usability to spring and early fall as well. The fit is boxy, and the extra length will be appreciated by those riding more adventure-touring and dual-sport machines. The Adventure Mesh is using CE-rated armor in the shoulders and elbows, and the sizing is quite generous, so bigger riders will have plenty of room.
