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.

    Better than expected!

    We all know they make great bags but this one is out of the box (literally!).

    The waxed canvas is a treat and the size is great for two people and all their parephinalia.

    Couldn't recommend it more highly.

    S-tier bag. Has just enough room to fit all my gear. My shoes and lever belt take up the most space so I like how this bag has dedicated compartments for them. Yes, the belt holder does fit a lever belt. Material is top notch and 99% of the bag I'm happy with. However, I do think the shoulder strap was a miss. Very thin, almost no padding at all. You can tell this aspect of the bag is not on par with how the rest of the bag is built. I solved this by buying a replacement shoulder strap with more padding.
