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.

    I don't like the material, the zippers are too big and get stuck, and it's too heavy even when empty.

    Blue collar job? Hitting the gym before work? This bag is a must! I can fit my work boots, towel, work clothes, and all my toiletries in the Core Duffel and still have room left over. By far, the best purchase I have made for gym gear!
