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 10 shoes. The CORE51 (Large) will fit size 13 shoes. Larger shoe sizes will fit our PLUS Duffel.

    Bag is Dope!!

    Loving this bag. I've used a few duffel bags for my Gym bag and this one is by far the best. The quality of the build is awesome. Heavy duty material. It will last forever. The divider is a game-changer. I'm able to keep things separate and organized.

    I bought this as a Christmas gift for my husband and he loves it. He needed something big and sturdy to hold his gym clothes and work clothes and work boots, and this bag gets it done. His favorite thing is all the pockets to help keep everything organized.

    Highly recommend!

    The bag is very nice and extremely durable. One of my favorite features is the bag does not “collapse” when you open it up. You can really fit a lot in this thing and it won’t be stretching any seams. Fits all my lifting equipment and more.
