Great extra space. Always have the straps on, and the Space Bag when I travel. Probably the best upgrade to make!
Space Bag Bundle
Extra space when you need it. The Space Bag Bundle adds 9 liters of storage to any backpack through the MOLLE attachment system. Built for shoes, wet gear, or anything that doesn't belong in your main compartment.
The included MOLLE straps secure the bag without bounce or shifting. Made from recycled nylon that handles weather and wear. Simple attachment, reliable hold, practical storage.
Perfect for gym sessions, travel days, or when your gear outgrows your bag. The Space Bag keeps dirty items separate while staying accessible.

QUESTIONS
We answer your most common questions.
What makes Kilometer backpacks different from other brands?
Kilometer backpacks are designed specifically for run-commuters. Every bag features a modular system that lets you customize your setup with accessories, and our materials are chosen to handle sweat, rain, and daily abuse while still looking sharp at the office.
Can I add accessories to any Kilometer backpack?
Yes — all our backpacks use the same MOLLE-compatible attachment system. Accessories like the Space Bag, Waist Pocket Belt, and Bottle Holder work across the entire range.
What is your return policy?
We offer a 30-day return policy on all unused products in original packaging. Custom kit bundles can be returned as a complete set. Shipping costs for returns are covered by the customer.
Do you ship internationally?
Currently we ship within the EU and Scandinavia. International shipping to other regions is planned for later this year. Sign up for our Members Club to be notified when new shipping zones become available.
