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.

    Love this bag

    Like the title states, I love this duffel. I like bringing a gym bag in with me for extra storage and carrying space, but I didn't want a huge duffel that got in the way or became a tripping hazard inside the gym. I was using a sling, but it was too small for most things. This bag perfectly holds my water bottle, preworkout supps, and other gear. It's also extremely easy to slide my keys and wallet into the side pocket. 10/10 bag. I even use this on small overnight trips, as well. Build quality is amazing, too.

    Excellent!

    This is an AMAZING bag! Strong. Sturdy and well made. Originally we ordered a smaller version but upon arrival it was clear the medium bag was too small for what was needed. The exchange process was very simple, quick and truly made me believe in customer service again. What a great company.! Proud to own an American made excellent product! Thank you!!

    Perfect size

    I only stay at the gym for 45 minutes or less. So the size is perfect for the few things that I need to store. The water bottle holder is the number 1 reason why I bought the bag.
