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.

    Hi quality Duffel

    I have to say this is a near perfect Duffel bag!!! The company is top notch with their customer service. I wanted to exchange something and they were more than accommodating in assisting me in the process. The quality of the bag is top notch. This bag will no doubt be the last one I purchase as I believe it will stand the test of time.

    Just 2 suggestions in design. First a solid handle at one end of the bad to make it convenient to pull out of airplane carrying on bin or just to grab and hold it vertical and second use the larger zippers on the side storage pockets instead of the small zippers which can be difficult to close and open around the corners.

    Seriously a great bad!!!

    Exceeded my expectations!!

    Best gym bag I have ever owned (and I’ve had many). The bag’s design and build are excellent. Not only is it easy to access items in the bag while working out, but it doesn’t fall over onto the floor like my backpacks did. I only wish I had this bag years ago. Well done!!👍

    Best bag ever

    This bag came in handy more than any other one. Its great for throwing overnight things in or just loading up items for the day. The wax coat makes it look amazing and it is 100% waterproof. I have three of these bags and backpacks and i wont buy another bag other thatn KNKG
