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 Bag

    Love this bag, it stores a lot and it doesn’t get too bulky. I love the shoe compartment, the bottle holders and the laptop storage area. Attached is what I usually carry to the gym and it all fits perfectly.

    Awesome Gym Bag!

    Wish I found this sooner. Shoulder strap is comfortable, the material feels durable, variety of pouches/zip pockets for organization of smaller items. And the perfect space for all the gym essentials.

    Also the zippers open effortlessly, it’s a nice touch.

    Love it!

    I use this bag to carry essentials to the gym and to Taekwondo classes. It's big enough to carry everything I need but still fits in a gym locker. Construction seems sturdy.

    I love this mini!

    I didn’t need the larger duffle and chose the mini and it did not disappoint.

    Customer service was 10/10 and they sent me measurements to determine if my lever belt would fit and it did.

    Great bag, great company.
