Now a yearly tradition that debuts once the days get shorter and the weather gets wetter, Nike Running unveils their amazon Flash Pack. The 2015 collection features a new feature to the modified running silhouettes designed to be high-vis and water-resistant: multicolor reflective material. Always with standard silver reflective 3M detailing in the past, this amazon Flash Pack including the LunarGlide 7, Zoom Pegasus 32, Zoom Structure 19, and Free 5.0 gets colorful with the light-up rainbow effect underneath each model’s water-resistant mesh upper. Along with a range of Flash apparel, the Nike Running Flash Pack for 2015 in men’s and women’s sizing is available now on nike.com
