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.

    loving my gym bag. Well made. I have gone through a gym bag a year but was buying cheap bags. The way this bag is built, I think this may be the last bag I have to buy. lots of room and plenty of pockets to store things.

    These bags are so well designed and pit together, im actually blown away. I wS worried the medium might be too big but its perfect- even the sizing of the bags is different in the best way possible.

    Excellent gym & recovery bag

    I’ve been using the CORE PRO Duffel Mini as my everyday bag for lifting, sauna, and cold plunge, and it’s honestly been perfect. It’s compact, easy to keep well organized, and holds everything I need for a full gym and recovery session. The quality feels excellent, and I constantly get compliments on it at the gym. A buddy of mine had one, after seeing his I ordered one, (and glad I did) easily one of my favorite pieces of gear I’ve bought this year. If you’re considering getting one, buy it! You won’t be disappointed.

    Perfect Multi-Use Bag

    I've bought (and returned) so many bags, I can't even begin to explain it. None of them could do what I thought would be a relatively simple task: take me between the gym and work (in either direction) comfortably and stylishly without making it look like I'm moving in somewhere. The KNKG CORE Duffel Medium 35L was the keeper. Shoes, outfits, som gym gear, laptop, dopp kit, computer cords/chargers -- they all fit in easily. If you are on the fence about this bag, buy it.
