We have designed this bag with a unique and large reflective branding on the front of the bag. With reflective branding, you can avoid any accidents on the road in the dark while walking or riding.These are the little things that make such a huge difference. The little lock, well hidden inside the water bottle pocket helps frustrate the efforts of seasoned thieves, while making it very easy for you to operate. This little device has saved many Trinity owners great heartburn.
