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.

    The forst thing that surprised me was the wuality and thought put into iust the pacaking.

    Once i felt the material of the bag and opened it, it was game over. This is by far the best duffel bag i have ever owned.

    Despite this being the mini, there is so much room for gear: weightlifting shoes, knee sleeves, straps, tape, tape, water bottle, snack and even an OVR speed device all fit without feeling crammed at all.

    Dont think about it anymore and get the bag, its absolutely worth it!!

    Ps: the patches that came with the bag are also great quality and are appreciated :)
