Rock Travel Bag
The Rock Bag is a messenger-style travel bag designed to address the key needs of travelers: security and organization. The design combines a structured form with storage solutions for different items.

The Rock Bag features multiple storage components both inside and out:
-
Zipper pockets
-
1 slide-in compartment at the back
-
3 internal dividers
-
Threaded lock pocket in the front for important items
-
Small item pouch inside (for keys, wallet, cards, etc.)
This organization system keeps items neatly separated and easily accessible to meet the user’s needs.
Using CAD, I designed a threaded lock mechanism to secure important items in the front, making them harder to access without intentional effort. The lock functions like a screw thread, where unscrewing it releases the closure, and it is designed to be easily removed or replaced with different shapes and styles.
A custom-made adjustable tensioner was designed to fit the 2” strap, making it easier to secure and adjust the bag’s height.
Through concept sketching, I wanted to use striking colors for style while maintaing the functions for a travel bag. I created rapid prototypes of each iteration that tested the threaded component as well as testing for size, function, and patterning.
After prototyping, I created the patterns and tech pack in Adobe Illustrator to figure out sizing, seam allowances, and manufacturing. The Bill of Materials (BOM) helped me get a sense of material costs and callouts for different components needed for creating the bag.
Through multiple prototypes, I resolved pattern issues and selected durable ripstop nylon as the lining material for storing items inside the bag.
