Light, fast and built to move

The Spin Bag 18L is the ideal low-volume pack for athletes who want to travel light without sacrificing protection or organisation. Designed for streamlined movement across commuting, training and daily life, it delivers everything you need and nothing you don’t — waterproof protection, thoughtful pocketing and exceptional load balance. Crafted from 600D recycled polyester with a TPU coating, it shrugs off downpours and wet pavements while keeping your essentials bone-dry and easy to reach. The ergonomic geometry spreads weight evenly across your back, eliminating hotspots and helping the pack move with you rather than against you. At just 950g, it’s built for fast-paced days when you want a pack that’s agile, comfortable and compact, yet robust enough for daily use in the city.

Cities move fast — but Kilometer moves faster. Born in Sweden in 2015, they started out as IAMRUNBOX™, the team that turned the humble commute into a daily training session and made run-to-work culture not just possible, but genuinely practical. While others were stuck in traffic, Kilometer were busy transforming pavements into running tracks, backpacks into performance gear, and everyday commuters into full-blown urban athletes.

Their mission has always been simple: make active living accessible and reduce our reliance on cars. But this new chapter takes that ambition further. Kilometer isn’t just building bags and accessories — they’re building an alternative. A future where movement feels natural, joyful and baked into the rhythm of the city. Where your journey to work counts as training, where the quickest route is your own two feet, and where gear works with your stride, not against it.

Guided by the principles that powered their early success — including an ISPO Award for the Everyday Rolltop and the responsibility that comes with being a Certified B Corporation™ — Kilometer is doubling down on products with purpose. Thoughtful materials. Minimalist, performance-driven design. And a belief that cities shaped for people, not cars, make life better for everyone.

This is gear built for the ones who move. The runners, cyclists, fast-walkers, stride-chasers, and anyone who sees the commute as a chance to feel alive rather than stuck behind a steering wheel. Kilometer turns everyday journeys into opportunities — and once you’ve felt that freedom, there’s no going back.
