The NOCTEX fabric is a laminate of microscopic retro-reflectors over an abrasion resistant polyester shell.
The NOCTEX fabric looks an inconspicuous dark grey during the day, but when light hits its surface after dark, it instantly illuminates brightly.
The light is reflected back to its source, lighting up your entire silhouette. This makes you highly visible to oncoming traffic and reduces the likelihood of low-visibility related accidents after dark.
