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.

    Perfect Efficient Gym Bag

    I love this bag for my bike commute to the gym. It's just enough space for everything I need and it fits perfectly into my bike's cargo basket, while being rugged enough that I don't have to worry about dirt or moisture from the road.
