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.

    Excellent

    I upgraded to the waxed canvas and it's been an excellent experience. Same great bag with nice little upgrades, and my nephew benefitted by a huge upgrade via my old one.

    Great bag !

    I use this to daily carry my required safety gear as a Sheriff’s Deputy. I put my gas mask, ballistic helmet with attached communications headset, radio and comms attachments, eye protection and riot face shield, and spare batteries etc. The material keeps water from penetrating into the contents inside and is durable from scuffs while stored in the trunk of my vehicle with other abrasive equipment and shuttled to and from my locker each work day.
