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.

    Tier One

    By far one of the best gym bags I have own. To be able to carry my lifting shoes, gym belt (main reason I bought the bag), with extra space. Makes gear accountability so much easier.

    Best Backpack Ever!

    My wife and I use this backpack for hikes, the gym, and general strolls around town. Not only is it beautiful, but it’s comfortable, fits neatly on both of us, and has plenty room to store all we need. Highly recommend!!

    Best backpack ever!!

    This backpack is such a godsend - it is super lightweight, yet fits all of my CrossFit essentials in one place. 12/10 would recommend, and am considering buying a second one in black to have ~variety!

    Perfect Backpack

    After my older mini teal King Kong bag was stolen, I knew instantly this is the brand to stick with. The KNKG Backpack Mini is absolutely perfect with all the pockets and compartments while securing your gym equipment. I’m an avid CrossFitter and have received a ton of compliments too from our gym members. I have an upcoming trip and plan on flying with it as well. Thank-you KNKG for a well-made backpack!

    Best gym backpack I’ve owned. The waxed canvas gives it a classy rugged look, but still has a modern touch. Big enough for all my needs. I would say that I’ll buy another one, but I’m sure this thing is going to last a long time. Definitely made me a loyal customer.
