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.

    High Quality and Perfect Size

    Fell in love with the color. Was worried about it getting dirty but seems was enough to clean. You can tell this is made of high quality material - zipper included. I trust this bag will last me a long time.
