Using the same proprietary denim manufactured by The Works, Inc. in Japan, as with our Ignition Blue Stretch Jeans. The Blue Tracker Vest was designed with the bikerider in mind. A set of 6 pockets on the vest, 2 of which are internal. 6-button closure up front covers the classic, heavy duty YKK double zipper. Zip open the bottom for a little extra space. Of course, we thought about the collar snaps so high-speed wind turbulence won’t cause the collar to beat the hell out of you.
