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.

    Perfectly Beefy Bag

    I got my hands on this bag and instantly knew it was a top notch product. Immediately I could tell the materials used were intended to keep this bag going for a lifetime. Basically, nothing about this seems cheaply done or even meant to build a “quantity” type of item. Quality all the way and I will be recommending KNKG to anyone when an opportunity presents.

    I Was This Many Years Old When I Learned Backpacks Could Do This

    I loved my old gym duffel the way you love a golden retriever that sheds everywhere and knocks over lamps — deeply, unconditionally, and at growing cost to my shoulder. It held my shoes, clothes, belt, and forty pounds of “just in case,” but hauling it felt like rescuing a golden retriever from a well.

    Then the KNKG Core Backpack in waxed canvas walked into my life and I felt like someone finally told me the M&M’s go IN the popcorn. A revelation.

    This bag holds my size 12s in their own sealed shoe dungeon, a full change of clothes, and my lifting belt clipped smugly outside like it’s showing off. Enough pockets that my stopwatch, headphones, wallet, and keys have never once had an awkward run-in. It’s organized, handsome, and aging like it’s trying to win a rugged-but-emotionally-available contest. Same, bag. Same.

    I no longer carry forty pounds like I’m auditioning for strongman. I carry one gorgeous, capable backpack, and I genuinely could not tell you where my old duffel lives now. Attic? Witness protection? We don’t talk about it.

    Every day I pick this thing up and feel a small, ridiculous flutter of gratitude. 10/10. Would let it hold my belt again.

    Great small backpack

    Took it on a trip with me and it's the best everyday backpack i could pick: tough, good looking, perfect size.

    Core mini

    I like the bad but wish I had gotten a larger version or a duffle bag instead. I can barely put my shoes and clothes in there. If I didn't carry shoes with me to change at work it'd be a good size.
