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.

    Even Fits My Leg Days

    Great bag, satisfied even when it’s leg day. Meaning I shove my lifting shoes in the lower compartment (women’s size 9) and thankfully they fit perfect. Even the belt slapped around the outside fits nice and I have a lever style belt and it actually stays. The two straps in the front hold it in well. Super satisfied. Green color is nice too. Hopefully bag will soften up, it is quite heavy and a little stiff but that just means it’s great quality.
