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 (25L and 33L) 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. The CORE33 (Large) Backpack can fit a belt up to 6.3"/16cm wide. The CORE25 (Medium) Backpack can fit a belt up to 5.9"/15cm wide.
And yes! Lever belts will work with this bag.
The CORE25 (Medium) Backpack fits shoes up to size 12 US mens trainers/runners comfortably. The CORE33 (Large) Backpack fits up to size 15 US mens.

The best gym bag for the active man.
- TBTimothy B.I recommend this productRated 5 out of 5 starsGreat for powerlifters
This bag fits my 10mm thick, 4” RDX powerlifting belt great, and has ample room for all my gym accessories.

Exactly what I was looking for. I picked bag mainly because it was designed to have a weight belt wrapped around it without looking weird or making it uncomfortable. Best part you can pretty much have any weight belt doesn’t have to be a KNKG belt. I use for my INZER lever belt. Overall was really impressed.

I have only had this bag for a couple weeks now but completely changed how I carry all my gear as a powerlifter I carry a fair amount of stuff and there are no problems and it’s far more organized than my old Nike duffel and the fact my inzer lever belt fits soo nicely on the outside of the bag but doesn’t affect the comfort of wearing the bag is perfect
