The rugged reflector Vollebak Solar Charged Puffer

The smartest safety jacket you’ll find, this three-layer, 20,000mm-waterproof Vollebak takes survival skills to the next level. Insulation from recycled plastic bottles copes with temperatures down to -40°C, but the killer feature is a phosphorescent compound that rapidly stores and re-emits any light it comes into contact with. The result: battery-free, instant visibility for up to 12 hours as soon as darkness descends.
