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.

    Albeit a little bit smaller than I was anticipating, Right out the box you can tell this is made of good, heavy duty quality.

    Excellent bag. I only wish there a was bungie drawstring on the water bottle pouch, bottle doesn't feel secure. Other than that exactly what I was looking for.

    Best built & smartest made

    I don't do a lot of reviews but this gym bag warrants it. Smartest design I have ever seen. Pockets that work and hold what they should. The weight belt slot is brilliant!! The water bottle pockets are perfect. The materials used are heavy duty and the zippers are effortless. I love this bag and use it every day.

    Great bag

    Great bag for my morning gym session. Perfect size for my gear, a towel, toiletries, and a change of clothes so I can shower and head straight to work. Super high quality!
