Why we carry it

We’ve been curating design-led pieces since 2009. Ucon Acrobatics is a Berlin design label known for minimal, city-ready backpacks and bags, built from recycled and vegan materials. The Phantom Series uses ECO-RFLX-900, a custom fabric woven with microscopic glass beads. By day it looks matte and dark; at night, headlights turn it into a highly reflective surface, so you are seen when it counts. The interior is light grey nylex, so small things don’t vanish in a dark bag.

Buy once: durability and care

Wipe with a soft, damp cloth; don’t scrub the reflective surface with abrasive cleaners. Empty the bag before cleaning and let it dry at room temperature, away from radiators.
