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.

    The Perfect Gym Bag

    For some time, I have been frustrated with the one or two gym bags I have used, and after seeing your ad, I knew this was the bag for me. True to its description, it is small enough to be carried easily into and out of a gym. It is deep enough to hold several items I use routinely while working out, such as lifting hooks, straps, and a water bottle. I could not be happier with the color, size, and construction. Excellent, well done KNKG

    The only bag you'll ever need!

    Adding my 10th KNKG bag to my collection, I can honestly say I never get enough of these bags! From exceptional craftsmanship to incredible durability, KNKG bags truly stand the test of time. Whether it’s for the gym, travel, work, or just everyday adventures, these bags always have my back.

    The waxed canvas feels like butter, seriously, unmatched quality. The thoughtful organization and smart design make them perfect for any lifestyle. I get compliments everywhere I go, and I’ve even converted several friends to the brand. Highly recommended!

    Bag is great and am using it today in the gym. Onky recommendation is that the water bottle pocket be tighter or be adjustable. My water bottles fall right out due to no tension.

    Bag does it all—carries everything and organizes everything perfectly.

    I have been considering various bag manufacturers, and I am very pleased with my choice of KNKG. Their bags are exceptionally well-designed. The external belt holder has significantly increased available space—quite an innovative feature.

    It’s absolutely perfect, it is as advertise. It is a tiny little duffel bag for grips, chalk, barbell clips… Jump rope, wrist wraps, all fit perfect perfectly for Travel… If you’re a Crossfit🏋🏾‍♂️ or any Jim person would like to bring your own stuff with you on the road when you travel this is fantastic and also it’s great for the gym. The dividers are absolute crack! If you have a big gym bag, get them! They will make your life so much easier and aesthetically pleasing on the inside for all the OCD like me!
