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.

    BBOAT!!

    I had this 25m Core bag in my shopping cart for months til I finally decided to research online (which was all positive reviews) and every time I see someone rockin it in the gym I get nothing but good feedback on it, took me awhile to pull the trigger bcuz I was waiting for some kind of holiday sale and now that I finally got it…it’s worth every penny!! Definitely satisfied wit my purchase.

    Everything I Need

    This backpack has all the space I need to carry my gym gear and BJJ gear.

    I also really wanted a backpack with a belt loop and shoe compartment and I thought this one looked the cleanest compared to the competition.

    Great new gym bag!

    Love my new gym KNKG! Holds all the things from extra shoes, lifting belt, jump rope, clamps and a place for all my smaller items for easy access. Water bottle pockets are big and deep as well. My Yeti 36 oz rambler fits perfectly with no issues. So far no issues and love the look.

    Core BPB Large Review

    I love this bag! Big enough to combine my work and workout bags together. Only wish is for vents in the shoe pocket. Also when the bag is hanging you cant pull the shoes out or the liner will fall through the bag. Some sort of retention would be ideal
