Spin Bag 30L

Yes. The main compartment is 100% waterproof with heat-welded seams throughout and a rolltop closure, built like a drybag. The front pocket sits beneath a waterproof flap with a YKK zipper for splash protection. The external back-panel laptop pocket is not waterproof on its own; in heavy rain, place the laptop in the internal padded sleeve inside the dry main compartment.

The Spin Bag 30L fits up to a 16-inch laptop and offers two carry options: a full-depth external back-panel pocket against your back for quick access, and an internal padded 16-inch sleeve inside the waterproof main compartment for heavy weather. Internal sleeve dimensions: large opening 28 cm wide, small opening 22.5 cm wide, 35 cm tall.

Yes. The Spin Bag 30L is engineered for cyclists who want a single 100% waterproof carry without needing a pannier rack. The 30-liter capacity holds a 16-inch laptop, change of clothes, lunch, two water bottles, and a rain shell; the contoured padded back panel and sternum strap stabilize the load while riding.

The Spin Bag 30L uses a three-compartment system: an external back-panel laptop pocket for fast laptop access, an internal padded waterproof laptop sleeve inside the main dry compartment for heavy-weather use, and a dedicated bottom compartment for shoes or wet/dirty gear separated from the main compartment so clean stays clean and wet stays wet.

Yes. The Spin Bag 30L has external MOLLE webbing that accepts these accessories: Space Bag (+9 L expansion), Waist Pocket Belt, Minimal Belt, MOLLE Strap System, the Large cube of the Packing Cubes Set, Carabiners, and Reflective Strings. The Packing Organizers Set, Quick-dry Towel, and Garment Bag are also compatible with the Spin Bag 30L but live inside the main compartment rather than attaching externally.

The bottom compartment is a dedicated internal space at the base of the bag for shoes, wet kit, or dirty gear, separated from the main compartment so clean clothes, your laptop, and everyday items stay clean and dry. Above it, the main waterproof compartment is a single space with an internal padded 16-inch laptop sleeve against the back panel; there are no built-in small dividers or sub-pockets inside the main compartment. For smaller-item organization, pair the Spin Bag 30L with the Kilometer Studios Packing Cubes Set (three cubes: 1.8 L, 2.7 L, 5.7 L) or the Packing Organizers Set (three pieces, 10.5 L total). A front pocket with a YKK zipper under a waterproof flap holds phone and keys externally for quick access.

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.
