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.

    Must be the best deal out there

    Perfect size for what I need, great pocket design, looks good, seems very well-made. And less than $100? Wow. I am wondering how the zippers will hold up, they seem a bit lightweight compared with the overall build of the bag, but so far no problems at all.

    Best gym bag!

    I’m always buying different gym bags hoping to find the “right” one for my usage. I was looking for a small to medium sized bag that was well made with enough storage. The 15L KNKG fit checked every box!

    Cannot recommend enough.
