The Rockgeist fabric selection now includes a UV optimized blaze orange that will resist UV fading much more then the previous VX21 blaze orange. The old VX21 used a blaze orange dye on a nylon base and had the worst UV resistance of all the VX21 colors. This new VX25 blaze uses different dye chemistry on a polyester base and is much more resistant to UV fading. Stay tuned for more details on this in a much longer post… But for now, enjoy your new blaze!
