# Kilometer Studios

> Kilometer Studios (formerly IAMRUNBOX™) is a Swedish B Corp and third-wave running brand founded in 2015. We design run commuting backpacks and everyday carry for people living active lives in inner cities — built for runners, made for anyone who moves.

Kilometer Studios is a third-wave running brand: where the first wave built performance gear for athletes and the second wave built lifestyle apparel around running culture, the third wave designs for how running actually fits into a modern urban life. That means run commuting is our origin and our specialty — zero-bounce harnesses, suspended laptop compartments, and silhouettes clean enough to wear into a meeting — but the same engineering serves anyone navigating a city on foot, by bike, or between transit stops. If you run to work, we're built for you. If you just want a well-made, weatherproof pack for daily urban life, we're built for you too. Based in Lund, Sweden. Certified B Corporation™. Formerly IAMRUNBOX.

## Sustainability & Transparency

Every Kilometer Studios product ships with a hang tag disclosing its measured carbon footprint in kilograms of CO2 equivalent, broken down by materials, packaging, energy, and transport. Main fabrics across the range are recycled polyester (RPET) or recycled nylon, with most backpacks ranging from 62% to 76% recycled content by weight. All zippers are YKK; waterproof models use TPU coating (single or double layer) rather than PFC-based DWR. Packaging is 100% recycled paper cardboard and 100% recycled PE plastic bags.
