Phosphorescent Running Cycling Night Jacket - FIREFLY

Subscription Save


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.

Phosphorescence is the phenomenon observed when a material continues to emit light after being illuminated. The Firefly Jacket was designed for running on dark, deep nights. Using a headlamp, for example, you can recharge the fabric and then let the jacket glow. You can also have fun writing or drawing on the jacket.

Performance and membrane

Windproof and water repellent

The Firefly jacket is windproof, 5000 Schmerber water repellent and 3000 MVP breathable. It has an internal membrane. It also has waterproof zippers and taped seams to ensure complete water resistance. It is also packable in its chest pocket. It then turns into a small easily transportable ball.



Apply any light source to the textile to recharge it: sun, light from a phone, headlamp, flashlight etc. Depending on the intensity and the time under this source, the jacket can keep the light for up to 30 minutes. Beyond that, the jacket emits a "phantom" white


Inspired by fireflies

The Firefly jacket is inspired by the bioluminescence of fireflies. Their light is produced in the abdomen by a specific reaction. In the animal kingdom, this light is used to attract potential sexual partners. To date for humans, we have yet to scientifically prove this function with the Firefly jacket.



Avoid heat to protect the internal membrane. No washing at over 30 ° C, no ironing, no dryer. The jacket is made from 100% polyester.
