We answer your most common questions.
The Packing Cubes Set includes three cubes in graduated sizes: Small (1.8 L, 41 g), Medium (2.7 L, 56 g), and Large (5.7 L, 84 g). All three cubes share a uniform depth profile so they nest and stack consistently inside a backpack. Total combined weight is 205 grams.
The main fabric is 75D recycled nylon with a polyester mesh panel for ventilation, and the lining is 210D RPET (recycled polyester). Zippers are YKK. Total recycled content is 52%.
Yes. Each cube includes a mesh panel that allows continuous airflow to moisture-prone items, helping keep gear separated from dry storage and reducing odor retention during transport.
Yes. The Packing Cubes Set is sized to fit inside Kilometer Studios backpacks and is included in the Run Commute Ultimate Kit alongside the Backpack Pro 16. The graduated Small, Medium, and Large sizes nest together to organize clothes, accessories, and gear inside the main compartment.
Yes, but only the Large cube. The Large cube (5.7 L) has MOLLE attachment points and can mount externally to a MOLLE-equipped Kilometer Studios backpack (Spin Bag 30L, Spin Bag 18L, Everyday Rolltop, Pannier Rolltop, Backpack Pro 16) for overflow capacity without opening the main compartment, similar to the Space Bag. The Small (1.8 L) and Medium (2.7 L) cubes are internal-only.
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.
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.
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.
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.
Good sizes and great quality, highly recommended.
