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.

    A Bag that Will Pass the Test of Time!

    The Core Backpack is everything I hoped it would be. Having passed the 3/4 century point in my life. I have worked out in more gyms during the past 60+ years than I can recount. The KNKG Core Backpack is, without a doubt, the very best gym bag I have been privileged to use and I am certain it is a Gym Pack that will someday be passed on to my heirs! The waxed canvas it is made of is some of the best that I have seen and the construction is flawless. Gentlemen, the Waxed Canvas Core Backpack is a Bag you can be proud to pass on to your customers.
