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.

    Amazing bag

    I have struggled for so long with comfortability and style and this bag does it all. It’s the perfect size to keep with you as you workout, but big enough to hold all your gym gear. I’ve got a compliment on it just about everytime I go to the gym! THANK YOU KNKG for the amazing bag

    Backpack Large 33L

    Fantastic gym backpack with tons of space and smart organization. The 33L size is perfect for carrying workout gear, shoes, accessories, and everyday items without feeling bulky. The materials feel premium and durable, and it’s comfortable even when fully loaded. Great bag for the gym, travel, or daily use.

    Love it

    Great Gym bag, I researched all the different kinds of gym bags out there for months. Went back and fourth for a long time if this pack was going to be worth the price tag/too big. I wanted this to be the last fricken gym bag I buy....It definitely is great quality and big enough to fit my essentials but not to big for me to get disorganized, which was why I was getting rid of my black hole of a duffle bag. The shoe compartment was one of biggest sellers for me, nice to have my swampy chaulk and protein powder sprinkled shoes not touching my inhaler, your not thinking about ring worm when your trying to breath. Exercise induced Anaphylaxis eppy pen at the ready in the front pocket , how embarrassing it would have been digging through a duffle as your eyes are swelling shut. A place for everything and everything in its place, is sometimes more important for some then others. This bag helps put my mind at ease which is why I'm at the gym in the first place.
