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.

    Great for Commuting Military

    I’ve been really happy with this backpack for my day-to-day commute to the Pentagon. It has plenty of room without feeling overly bulky, and I can comfortably fit my lunch box, gym gear, and other daily essentials inside. One of the biggest positives for me is that it also meets military uniform requirements, so I can carry it while in uniform without worrying about compliance. It’s comfortable, practical, and has been a great all-around commuter bag. Definitely recommend it for anyone looking for a solid work and gym backpack.

    Great size and highly durable

    The medium 25L bag feels like a standard sized backpack. Has a good amount of pockets with plenty of room. It's a very durable bag. I also love the Belt holder. My only complaint is that since I have a small waist, my smaller belt makes using said room and pockets slightly harder to access when my belt is on the belt holder.

    This thing is perfect. Wish you made this in large with waxed canvas. I bought the waxed mini duffel as well and love them both.

    Durable, spacious, well designed

    As always, KNKG has knocked it out of the park. The redesign keeps all of the best aspects of the CORE bag, while streamlining small but meaningful features such as the top pocket, and the side waterbottle pockets. Also, the expanded velcro patch area is fun.
