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.

    Received this afternoon. Transfered all of my gym stuff to this bag, loved it! The functionality is amazing! I change from my work clothes into me gym clothes at the gym and it holds my boots and jeans plus everything else I carry for the gym. I really like the outside pockets for water bottles. Highly recommend, get one!
