It delivers the same proven longevity as our ballistic materials, with a vintage feel that gets better the harder you use it.

BUILT TO GO THE DISTANCE
Waxed canvas isn’t just for looks. It’s a proven material trusted for over a century. Water-resistant, tough by nature, and built to age with character. This isn’t a trend piece. It’s a workhorse built for the grind.

    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.
