Phosphorescence is the phenomenon observed when a material continues to emit light after being illuminated. The FIREFLY jacket is an avant-garde jacket designed with a phosphorescent membrane. The textile is ultra reactive to light and can be recharged under any source: sun, headlamp, light from a phone etc. The jacket will then glow in the dark. You can recharge the jacket as often as needed for practice and even play with the light on the textile. Inspired by the bioluminescence of fireflies, the jacket increases the wearer's visibility. It weighs only 185g and has many other sporting properties (detailed below). This technology designed for night sports makes it a pioneering jacket for decades to come.

    Night is a new playground

    Phosphorescent technology

    How does it work ?

    The textile reacts to light sources : sun, light from a phone, headlamp, flashlight etc.


    Depending on the intensity and the time under the light source, the phosphorescence can then last up to 60min. Beyond that, the jacket emits a "ghost" white


    The Firefly jacket was designed for running / trail in nature at night. You can also just play with the phosphorescence.
