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.

    2nd 51L bag in my arsenal.

    This bag along with my first are used for the gym and training equipment. I also use them for weekend getaways. Hold the correct amount for the 3 days.

    Amazing!!

    I love it!! After years of using the old single compartment bag from the big brand competitor, it’s awesome to have everything in its place. The Core duffle is perfect for the gym but I can see using it for so much more. Compartments for all my stuff and more. Best of all my stinky sweaty cloths don’t have to live with the rest of my stuff. I got caught in the rain leaving the gym and all my gear stayed dry and secure. Perfect.

    I’m thinking about using the Core on my next weekend trip.

    A great duffle

    Awesome bag that can hold my shoes and free up some space in my roller board. And this duffle fits under the seats of the airlines (if ya don’t stuff it too full). Holds up to the rigors or airline travel. 10 out of 10 I’ll be getting another because the wife keeps trying to take it ..

    Great Duffle CrossFit Gym Bag

    I bought the bag for my husband for Father’s Day and he loves it. He’s had numerous gym bags over the years, but I’ve not seen him as excited as he was when he saw this KNKG 51L bag. He’s already getting it organized, likes the space and dividers to keep everything organized.
