A travel pack that carries like a backpack, converts to a duffel, and handles like a side-carry bag. Straps tuck away completely. Built from DI-TEX 840D Carbonated Nylon, engineered for anti-scratch performance. Kickstarter funded, shipped to backers in 15+ countries.
Key facts
Convertible bags often fail: they try multiple things and do none well. Backpack mode compromised from duffel handles. Duffel mode awkward from bulking backpack straps. Conversion slow and fiddly, so people stop using it.
The brief was specific: design a bag converting between backpack, duffel, side-carry genuinely. Straps tuck away completely in each mode so it looks designed for that carry. Not a backpack with duffel handles. An actual three-mode system.
Added constraint: Reika's materials standard, performance fabrics engineered to spec, not commodity nylon. DI-TEX, their 840D Carbonated Nylon, baseline. And it had to work as hero item in a Kickstarter campaign. Design story legible in a 90-second pitch.
The design challenge on a multi-mode bag is always the same: how do you hide inactive straps. If not cleanly concealed, the bag reads as a backpack with add-ons rather than genuine convertible system.
We designed a tuck-away system that stows backpack straps into a sealed back panel pocket, completely flush and invisible in duffel or side-carry mode. Conversion fast and practical, not theatrical. Duffel and side carry handles built into structure, not added as afterthought.
The Camera Cube compatibility wasn't an afterthought. We designed the travel pack internal dimensions around the cube from the start.
The accessories range was designed as ecosystem, not optional additions. Camera cube integrates via gatekeepers. Shoulder strap and hip belt use the same harness attachment points. Rain cover stores in its own pocket. The system makes sense because every component was designed knowing what the others needed to do.

CAD Model
The gatekeeper system for Camera Cube integration uses internal attachment loops at specific positions inside the main compartment. The cube clips in, pulls tight, and doesn't move in transit. The same positions anchor the optional shoulder strap configuration when using the bag in duffel mode.
The shell uses DI-TEX, 840D Carbonated Nylon engineered by Reika specifically for anti-scratch resistance. The denier weight and construction give the bag durability appropriate for frequent travel without adding unnecessary bulk. Interior lining is 210D Nylon throughout.
The laptop pocket uses VELEX as an anti-scratch lining, protecting devices from abrasion in daily use. Four-way stretch and performance mesh are used in the harness system where movement and ventilation matter. The accessories range (camera cube, shoulder strap, hip belt) uses the same DI-TEX shell, so the full system reads as one product family rather than a bag with add-ons bolted on.
YKK hardware throughout. Zip tape specification consistent across the main bag and all accessories to ensure the same hand-feel and durability at every access point.

The main pack and accessories range were produced in Vietnam. Coordinating a multi-SKU accessories range alongside a hero product in production adds scheduling and QC complexity: the camera cube has to be tested inside the bag, the shoulder strap attachment has to be checked against the bag attachment points, and all components have to ship together.
We ran fit checks across the accessories range partway through the production run, pairing samples of each accessory with samples of the main bag to confirm integration tolerances held. When they did, production continued. When they didn't, we resolved it before committing to the full run.
All units inspected to AQL 2.5. Strap tuck-away system operation and zip function treated as critical attributes. Camera cube gatekeeper integration checked on a sample basis throughout the run.
The Modular Travel Pack launched on Kickstarter, funded, and shipped to backers. The three carry modes work as designed: backpack straps tuck away cleanly, the duffel handles take weight without the harness getting in the way, the side-carry handles are positioned correctly for the weight distribution of a packed bag.
The accessories range expanded the product story: not just a travel bag, a complete carry ecosystem for photographers and travellers who want a system rather than a collection of separate products.
