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.

    Great product, even greater interaction

    I original bought a bag from KNKG that ended up having a tear in the top pocket of the bag. After reaching out to customer service and interacting with Taylor, I was able to get the Core Backup Medium 25L, which has been fantastic for my workouts! I couldn’t be more grateful and excited to use it for a long time!

    The only backpack we agree on

    After decades of going through dozens of backpacks, this is the ONLY ONE that my husband (6', 210lbs) and I (5' 3", 140lbs) agree on. It is our absolute favorite not just for the thoughtful array of pockets, but because the fit works perfectly for both of our very different frames. We're each able to adjust the straps and load up the packs so that the weight is evenly distributed. Well done KNKG! We could not be more impressed!
