EXPANDABLE
With 9L of additional storage capacity, the Space Bag adapts to your carrying needs without overcomplicating your setup. The streamlined design expands to accommodate shoes, extra clothing, or gear while maintaining a compact profile that doesn't compromise mobility or add unnecessary bulk to your carrying system.
MOLLE SYSTEM
Equipped with the Kilometer MOLLE system, the Space Bag attaches securely to compatible backpacks with simple, intuitive connections. These reinforced attachment points distribute weight evenly and prevent shifting during movement, creating a stable expansion that feels like part of your original pack rather than an add-on.
BREATHABLE
The Space Bag features strategic mesh panels that allow air to flow freely through the compartment. This ventilation system prevents odors and moisture buildup—particularly important when storing shoes or workout gear after activities. Items stay fresh and dry, ready for your next session.

ASKED
QUESTIONS
We answer your most common questions.
Which Kilometer Studios backpacks is the Space Bag compatible with?
The Space Bag attaches via the Kilometer MOLLE system to every MOLLE-compatible Kilometer Studios backpack: Spin Bag 30L, Spin Bag 18L, Everyday Rolltop, Pannier Rolltop, and Backpack Pro 16. The reinforced attachment points distribute weight evenly and prevent shifting during movement, so the accessory rides as part of the host pack rather than as a loose add-on.
How much extra capacity does the Space Bag add?
The Space Bag adds 9 liters of external storage capacity to a compatible host backpack. It measures 25 × 41 × 1 centimeters flat and expands to fit shoes, extra clothing, or post-workout gear while keeping a compact profile against the back panel of the host pack.
Is the Space Bag waterproof?
No. The Space Bag is built from 75D recycled nylon with a YKK zipper and includes mesh ventilation panels, which prioritizes breathability for shoes and damp gear over waterproofing. For wet-weather coverage of the Space Bag and the host backpack together, use the Kilometer Studios Rain Cover as a separate accessory.
What is the Space Bag designed to carry?
The Space Bag is designed as an external expansion pocket for shoes, post-workout clothing, gym kit, or travel overflow that you want kept separate from the main compartment of your backpack. Strategic mesh panels allow airflow through the compartment, which helps prevent odor and moisture buildup from shoes or damp workout gear.
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?
Most of our backpacks use a MOLLE-compatible attachment system. Accessories like the Space Bag, Waist Pocket Belt, and Bottle Holder work across the MOLLE-equipped lineup (Spin Bag 30L, Spin Bag 18L, Everyday Rolltop, Pannier Rolltop, and Backpack Pro 16). The Trail Pack and Packable Rolltop are minimalist designs without MOLLE.
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?
Yes. Kilometer Studios ships worldwide. International orders are accepted from every country our logistics partners can reach; shipping costs and delivery times vary by destination and are calculated at checkout.

Great shoebag
Simple, but helpful :)
Quality and design
Super nice bag with a quality material and perfect design.
A good addition to runbackpack pros!
Think this was meant for the iamrunbox pro2.0 runbackpack but it works nicely on the former edition too with the elastic string and spacebag strap. Great for shoes, lunch box, jacket and doesn't bounce around when you run. Like any packing, be sure to pack the heaviest item at the bottom!
Great completion for the iamrunbox
If you ever run out of space, the space bag is your friend. It is also great to put your dirty shoes or clothes in it an keep the runbox clean! It is also easy to put on the runbox with the straps, which keep it very tight at the box.
