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.

    Impressed

    I've been really impressed with the KING CORE Medium 35L Duffel. It's the perfect size of the gym without feeling oversized. The bag feels premium, holds its shape and feels like it's made to last. There's enough organization to keep everything easy to find. Highly recommend!

    Best all around bag for sports

    I don’t just use it for the gym. It works great as a beach bag, the sand brushes right off! and also a range day bag! Fits all my gear and safety equipment. The quality of this bag means I’ll be able to use it for a long time to come! Definitely planning on getting the backpack

    The best gym bag out there!

    King Kong thought of everything your gym accessories need with these duffels. This is my fourth duffel from them and the waxed canvas is so cool! Best gym bag out there!

    Great Bag

    I needed something to use for work, and holding uniform when I changed for gym time. It works great and motivates me to get after it.
