It's never a bad idea to stack the deck in your favor, and the MIL-SPEC 2™ Vest stacks it with two different high-visibility options. Form-fitting and breathable, the four-way stretch polyester chassis allows the vest to be worn over your riding jacket, working with its existing vents. The snug performance fit eliminates wind flap, unlike the plastic safety vests of yesteryear. Engineered with the goal of "visual conspicuity," its HiViz body is paired with retro-reflective side and back paneling to aid in being detected in low-light conditions. YKK® zipper. Sublimated graphics. Reflective heat transfers. See and be seen in the MIL-SPEC 2™.
