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 bag

    Really well built. Handsome bag sturdy holds a lot very convenient for the gym or as a weekender bag. We’ll probably also use as a ski bag to hold a lot of my gear this season. Highly they recommend.

    Last bag for life

    I’ve been training in gyms for the past 27 years… through all of my competing in bodybuilding/powerlifting Ive gone through gym bags of all types from tons of different brands. Some were ok, most were absolutely sh*t… after getting this bag I can confidently say every other bag I’ve ever used was garbage compared to my waxed canvas duffel. This bad will likely be here long after I’m dead/gone. High quality craftsmanship & material. Buy this bag, you won’t regret it!
