This backpack is designed for serious lifters who crave serious organization.

This gym bag works harder than you do. This is the best and most functional gym bag you can find.

This is the best gym bag for powerlifters. Many amazing features that set this bag apart from its rivals. The outer material is tough, durable, and lightweight while also being water resistant and easy to clean.

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 KNKG 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 10 US mens trainers/runners comfortably. The CORE33 (Large) Backpack fits up to size 13 US mens.

    Huge success

    This was a gift for my son on his birthday. He opened the box and immediately transferred his gear to the new bag. He was very happy with the size and features of the bag. He took it to the gym the same day he received it.

    Worth it!

    I’m in Australia and had the bag shipped here. I’m about 3 weeks in to daily use as my gum bag and am glad I spent the money. Build quality is great, fits all my gear without any trouble, and looks great

    Core Bag Review

    I needed a bag for work and hit the gym afterwards and Core bag fit all what I needed. The side pockets were able to hold my 40oz beast tumblers with ease. Plenty of room for my laptop , files and my gym clothes. The material of the bag and zippers will last for many years. I have tried other bags and I feel like I wasted my money because this bag does it all.

    Fantastic Bag!

    I’ve been looking for awhile for the perfect bag that accommodates what I need to go from office to gym or vice versa. I’ve purchased adidas, Nike, Gymshark and others. Nothing has lived up to what I’ve needed until my KNKG Core bag. I can store all my things AND it conveniently holds my lift belt without sacrificing bag space. It’s the final boss of gym bags.
