FAQS

The CORE Mini Duffel is specifically designed to fit the KNKG weight belt. We don’t recommend using it with other belt brands. If you’re using a different belt, we suggest upsizing to the MEDIUM or LARGE CORE Duffel instead.

No - we don't recommend the mini size for shoe storage. If you're packing shoes we recommend checking out the medium or large size duffel.

    Great All Purpose Bag

    I purchased this bag primarily for gym clothes. I’ve found the bag to be of great quality which is easily seen and felt. The zippers, the seams and fabric materials are built well. Combined with the divider panels, the bag has many compartments to easily organize your gear and maximize the space.

    I highly recommend as a gym bag or weekend travel bag.

    Like the size and pockets, but zippers feel cheap compared to my old King Kong bag.

    Checked all the right boxes

    I highly appreciated every little detail of this bag. Starting from the outside, the belt slot is genius, finally a duffle with tall bottle slots (other brands I've tried is much shorter and bottles tip out). The overall quality of materials feels very durable and cleans very well. The interior is very well done, not too overly complicated, no compartments that can potentially leak into others, the shoe slot is designed great. Overall my favorite gym duffle. Highly recommended.
