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.

    Perfect Size

    Bought this bag to replace my work bag and it’s awesome. Holds everything in so many different pockets where as my last one only had two. Keeps my bulk things separate from my chargers, power bars and anything else I’m packing. I’d definitely buy another

    Carry On!

    I recently used my 51L bag for carry on travel. It fit into the overhead storage while holding 5+ days of cloths, gym wear and personal items.

    Better than expected

    I’m very pleased with the bag. Great design, ample room and quality materials. The first time closing the zipper, I could tell this is a very well made bag.

    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.
