FAQS

The main difference is the unique weightlifting belt attachment. This feature allows the bag be used as normal, while carrying a cumbersome lifting belt on the outside. Other changes are the volume (35L) and the layout.

Most of the materials are the same as used in other King Kong bags. YKK zippers, heavy duty buckles, nylon lining and webbing are all the same. In the CORE range, we have gone for a lighter 500D nylon outside and a new velcro logo feature that allows you to go 'incognito' with your own patches.

Measure the widest point of your belt and its length.

The CORE35 (medium) duffel can fit a belt up to 6.3"/16cm wide and 45.7"/116cm long.
The CORE51 (large) duffel can fit a belt up to 6.7"/17cm wide and 45.7"/116cm long.

A lever belt can fit, but you should count the lever into your measurement.

The CORE35 (Medium) will fit size 12 shoes. The CORE51 (Large) will fit size 15 shoes.

    Disappointed

    Purchased the Core 35 about 11 months and am disappointed. I really wanted to love this bag and this is a major bummer given the hype and price point.

    The Velcro that supports the belt frayed and destroyed the bottom of my Rogue USA belt. Other reviewers have noted this design defect as well.

    Purchased a new Rogue 3” Ohio belt that should fit per KNKG’s specs and it doesn’t as it renders the side pockets and water bottle holders useless. The belt is also an absolute nightmare to get in and out.

    The water bottle holder elastic becomes stretched and loose over time making the pockets pretty much worthless as well.

    Buyer beware on making this purchase. Back to the drawing board for me.

    Core 35

    should have bought core 51 duffel. the core 35 is great and will hold up for a life time, only thig my weight belt doesn't fit completely in the side slots, it sticks out 8'' or so. No big deal just a little funny looking,

    Lots of Pockets, Right Sized

    There are dedicated pockets for my phone, water bottle and weight belt. The bag keeps things organized.

    I like the shape. The bag is shorter than the competition, but it’s wider. It’s easier to carry while having room for everything.
