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.

    Winner!

    My husband loves to workout and I’ve been looking for a stylish sturdy gym bag for him and I found it! Purchased this for his birthday and he approves, and is definitely a fan. Highly recommended!

    Great materials, wonderful construction

    I absolutely loved the way this bag was made. My only issue is that even the smaller duffel was a little too big for my Jim’s lockers. I’m going to switch it up and order the backpack and give that a try. But you have no reason to doubt the quality of these amazing bags.

    Love my KNKG duffel. I had to exchange for the 50L bag. The 35L was not quite big enough to carry my size 12 shoes. The 50L is perfect. The bag is well made with plenty of pockets and storage for all the things you need at the gym.
