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.

    Best gift

    Bought this for my boyfriend and he began using it instantly for the gym! Great size to fit a water bottle, change of clothes, towel, and shoes! Very sturdy and quality bag that should last him a while.

    New boxing bag

    After trying many flimsy, floppy bags, this one fits the needs. The divider separates my gloves from my wraps and everything is tidy. The end pockets are great for the small things. It is not awkward to carry either when full or heavy. I now have one for weight lifting also.
