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.

    Best Gym / Fitness Bag Ever

    I spent hours looking at gym bags from well-known bags like Nike, UA, and random gym bags of various prices and styles on Amazon. Nothing was fitting what I was specifically searching for. I found KNKG on Amazon and decided to check out their website and instagram. The price was a bit higher than my budget but after watching videos and comparing photos, I knew I wouldn’t be happy with any other bag. I had a hard time deciding which color I wanted and if I wanted the medium vs large. The photos and videos on their website and IG were helpful in helping me make that decision. I have had this bag over a month now and it has been worth every dollar spent. The quality is exceptional. I love the neutral, monochromatic look of the beige/tan color. It’s beautiful. I’m happy I went with the medium. I was worried it would be too small to fit my gym equipment and would need to exchange it for a large, but once I received the bag and loaded everything in it, I was pleasantly surprised how much it can actuality hold. I was hesitant the large would be too big for me. The medium is perfect in every way. I purchased the beige bag dividers, as well. I’m so glad I did. I’m an OCD organized person and this looks so clean and easily accessible. I love that I don’t have to carry around my 40L water jug. It fits great in the side pocket. I still have so many extra, empty pockets if I need more space for other items to keep from feeling cluttered and like I’m endlessly digging to find the item I…

    Love this bag!

    I know it’s a small size but I can fit a lot of things inside of it and I prefer a small size bag so I don’t have to lug a big bag around. I’m also able to get my belt to fit. It’s perfect and I love it.
