Our lightest weight full length zipper choice, 30% lighter than our normal full length jersey zipper. The zipper's small/lighter coils and tape helps eliminate zipper bulge by easily conforming to your body. When the zipper's pull tab is in the down position, it locks the zipper mechanism, preventing your jersey from opening more than desired. Another added benefit is when the zipper tab is flipped open it's very easy to open your jersey with one hand.
