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 it!

    The mini duffel is perfect for my gym needs. The numerous pockets are super convenient to stash my gear and get to it when needed. I’ve gotten several compliments and recommended they check out the website. I definitely want to get one of the backpacks next. Thanks for making such a great bag!

    At first

    Smaller than what I thought it was going to be at first I wasn’t impressed and was going to return it. Then used it for a few times and I can fit everything in there. From belts, straps, powder, keys, water bottle, towels, head phones and with room for more. It’s small compact and honestly I love it.

    Excellent overall

    Excellent bag. Very organized. One thing I would change is the zipper pocket on the side where you put the belt could span the entire length of the height of the bag, not just part of it. People can choose to either open it all the way or part of the way. Opening it all the way gives more versatility and accessibility, in my opinion.

    The perfect size

    I didn't want to have a huge bag, but this size is surprisingly versatile! I've got my Theragun, plus straps, hooks, towel, belt, chalk, and some room to spare. I can set it down without feeling like I'm blocking access lol
