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.

    Only Bag I Need.

    I’ve gone through a lot of gym bags over the years, and most of them fall apart, smell terrible, or just don’t fit real lifter needs. This one surprised me. The Core KNKG waxed canvas bag feels different right away. it’s got that rugged, broken-in look like it actually belongs in a gym, not just a locker room. The material is tough but still clean-looking, and it somehow manages to look better the more you use it instead of worse. What really sold me is how functional it is without being overdesigned. Everything has a purpose. Shoes don’t stink up your clothes, smaller pockets actually hold things where you expect them, and it doesn’t turn into a black hole when you’re trying to grab something quick between sets. I run a pretty busy schedule as an early morning baker and carry a lot- lifting gear, extra clothes, sometimes even food and this bag handles it without feeling bulky or flimsy. I don’t like how big duffel bags are but this bag feels like one with the backpack functionality which is what I don’t know I needed. It’s one of those pieces of gear you don’t realize you needed until you have it. Most bags feel disposable. This one feels like it’s going to stick around for years.If you’re serious about your training and want something that matches that energy, this is it.

    2nd Bag, JUST AS GREAT

    I ordered a black version of the 33L core bag as a gift for a friend after he loved mine. He was SUPER excited when he opened it. Works much better than a duffel for him as he rides his motorbike to the gym

    The Natty color is absolutely awesome. I couldnt be happier with this bag! Everything from the material, to the storage space, to the pockets, zippers, etc are so worth the money.
