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.

    One of the Best Duffles I’ve Ever Owned

    This duffel is outstanding. The waxed canvas not only looks great but feels great too, and carrying it honestly adds a sense of pride. The build feels premium, the size is perfect, and it just gets better with use. Hands down, one of the best duffles I’ve ever owned.

    The delivery was absolutely top tier. The packaging itself gives an awesome factor. On top of that, the extra items are a nice touch. The wallet and keychain are high-quality, but the box is something that you don't expect. I walked away from the transaction feeling like I actually won, in a current economic climate that leaves you feeling taken advantage of a lot lately. The entire experience, from product to presentation, is simply next level.

    10/10 Would recommend. Price isn’t always about just the item. In this case, it’s about the way a company treats you, the experience they create, and the thought they put into every detail. KNKG delivered all of that here. This is a master class in how to earn a customer for life.
