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.

    Durable and Convenient – The Ideal Mini Gym Duffel

    This is my second duffel bag from KNKG. My first was the Plus Duffel, and I absolutely loved it for its durability and the number of compartments for all my gym equipment. Because of that, I decided to purchase the CORE Duffel Mini 15L—and it definitely lived up to my expectations. The quality is solid and feels durable, not cheap at all. It’s lightweight, easy to carry, and the perfect size for my minimal gym essentials. I also like that it has side pockets and still manages to fit my lifting belt.

    I’d recommend this bag to anyone looking for a smaller option on days when you don’t want to lug around too much but still want something reliable.

    This thing is so well built and the space is incredibly balanced with the somewhat compact size of this duffel. It is like the tank meets Ferrari of bags.
