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.

    Awesome bag

    This is my third KNKG bag - I continue to upsize as I add more and more training gear that I need to carry around. This is a great training bag and has so much room. I’ll always choose KNKG bags given the quality and durability of the product.

    Perfect Birthday Gift !!!

    Got this bag for my boyfriend for his birthday and he is obsessed! His old backpack was literally falling apart; he loves the duffel style and how many components are incorporated into the bag like the shoe compartment & belt holder. He’s also able to fit his work clothes & shower stuff in it as well for workouts before work. 100% recommend !!!
