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.

    My new favorite bag

    Comfortable on the back and Carrie’s everything I need.

    I wrap my belt around it just like the pictures and my shoes stay protected from everything.
