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.

    Love this bag

    This is my second Core mini purchase. My dad saw mine and loved it and wanted it for travel, so I got it for him. He loves it because it holds just enough for a long weekend. I mainly use mine for gym purposes, but have used it as a carry-on when traveling too. I wish it had a strap across the back to attach it to my suitcase handle, but otherwise, this bag is perfect.

    Love the core waxed duffle, well made and well thought out, there’s a pocket for everything! I purchased it for a gym bag but will use it for light travel as well.

    Great looking bag

    Love the color and feels lux and durable. At first I thought the bag would be too big and almost ordered the mini but it’s the perfect size. Fits everything I need!

    Big without being too big.

    The bag is well made, and well thought out. It can hold a lot without being to cumbersome. Can easily walk through the gym door with my 35L and the mini. Great products all the way around. Customer service is top notch too!
