Simply Amazing.Eben C.

“The bag is great! Feels well-made and durable. Got the belt to go with it and it fits perfectly without giving up any extra space.”

Extremely durable.Arie K.

The pockets are designed intelligently and make for excellent organization. Works best when you pair with the dividers. Highly recommend this bag!

    No Bag

    I wish I could actually review this bag but unfortunately, I never received it. I’m tried to contact the company but no response-I wish there was a an actual living person I could talk to but no phone number. The tracking info says it never reached the USPS location and no further updates as of a week ago. I order this for my son’s Christmas present 10 days before Christmas thinking I had enough time but no present for my son. I hope this review get someone's attention and I hope my son gets his Christmas present before January…

    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,

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.
