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 little personal item pack for traveling with gear

    The combination of a trolley sleeve, easy plane access, and dimensions that work well as a personal item on airlines around the world makes this a great option for carrying gear of all types for vacation travel, especially if you are looking for a small bag with two water bottle pockets. The bag will work great for destination carry for a wide range of items, and because it is self standing with easy access it works great as a car bag, beach bag, or other places you might want to have quick access from the top.

    CORE Backpack Waxed Canvas Mini 13L

    The perfect compact gym bag

    From the moment this arrived, I knew I was in for a treat. The packing alone showed a high level of care and attention to detail before I even saw the backpack itself. Once unboxed, the quality and construction of the bag absolutely blew me away. The waxed canvas material feels incredibly premium, rugged, and built to last through daily wear and tear.

    I use this for the gym to pack just enough for my essentials. It perfectly holds one pair of shoes, two water bottles, my headphones, keys, a lifting belt, and a small towel. Despite holding all of that, the bag is not heavy at all and feels incredibly sturdy on my back. It’s a great little compact bag.

    I honestly have no idea why I waited so long to purchase one.

    What a bag!

    Perfect Gym Bag

    This has become my perfect gym bag. Easily carries whatever I need for that day, even on leg day when I carry my lever belt, knee sleeves, shoes, and more. Enough space and structure in the main compartment and the smaller area are perfect for the other things you need (air pods, lock, keys and wallet, tape). So glad I pulled the trigger on this bag. Worth every penny.
