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 bag!

    I got the large and it was the right choice since I have multiple shoes at the gym. My favorite feature is the weightlifting belt slot on the outside so that it doesn't take up space inside the bag.

    With the dividers it makes organizing even better.

    Great

    Slightly smaller than expected. Not a bad thing, I didn't want a huge bag. But if you need a lot of room, definitely get the bigger one :)
