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.

    CORE Duffel Waxed Canvas Mini 15L

    Definitely a quality bag. I really enjoy using this bag for my gun stuff, (edc storage), even though I think it was meant to be a gym bag. Very Happy with this man bag purchase, I think it's going to last a lot of years.

    The last bag you’ll need!

    I’ve been searching for a durable capable varsitile bag. There are many that offer those attributes with varying degrees of success, but KNKG does it the best AND in the size I needed. My gym won’t let you bring larger bags into the lifting area and the 15L mini is small enough to pass the rule and still keep al of my things organized and on my person.

    Great bag that will last a lifetime

    This bag will last longer than you. My last one lasted eight years, and I’m pretty sure it’s still going strong somewhere after it was stolen out of my car. It’s great for organization, incredibly durable, and has plenty of room for all your shaker bottles. I’ll definitely be buying another one. I already have one for the lifting gym and one for the climbing gym, but I could always use another. It’s just a really solid bag.

    Great idea, just poor execution. Purchased the CONQUER 40L and was so happy. Thought this bag would be “better”, but it falls short. Not sturdy at all, which I need since I carry a lot of my own equipment. Using as a range bag instead. Still an ok purchase. Just nowhere near as good as what came before.
