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.

    The most durable highest quality bag ever!

    I had my initial doubts at first seeing how there are so many different gym bags out there.

    Once I received it in the mail and opened up the box it came in, I was amazed at how well packaged the bag was.

    Finally used it for the gym and I must say I managed to pack so much into the bag it has so much room! And the quality! Top notch! Felt like this bag is super heavy duty!

    Will definitely buy again in the near future!

    Lives up to the hype

    As advertised! This bag has more storage space than my house. I’ve got pockets for days and have run out of stuff to put into them. The construction is solid and the real proof for me is the smoothness of the zippers. Anything with zippers worth its salt has bind free zippers and this does. Shoulder strap is the perfect length and love the OD green. This thing will out live me and holds everything I need. Best purchase this year for me.

    Tough!

    This bag is almost perfect. Weight, durability, color, organization, all perfect! The only drawback is that my shoes don’t fit at all. Not even close. Anyone over a men’s size 10 will struggle to get their shoes in there. So I just use that compartment as a wet compartment for my used clothes.

    Ideal bag for advanced gym goers

    The biggest shortcoming of most gym bags is organization. This bag coupled with the duffel divider is the ideal bag to organize your gear, shoes and clothes.
