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.

    Everything I Need

    This backpack has all the space I need to carry my gym gear and BJJ gear.

    I also really wanted a backpack with a belt loop and shoe compartment and I thought this one looked the cleanest compared to the competition.

    Great new gym bag!

    Love my new gym KNKG! Holds all the things from extra shoes, lifting belt, jump rope, clamps and a place for all my smaller items for easy access. Water bottle pockets are big and deep as well. My Yeti 36 oz rambler fits perfectly with no issues. So far no issues and love the look.

    Core BPB Large Review

    I love this bag! Big enough to combine my work and workout bags together. Only wish is for vents in the shoe pocket. Also when the bag is hanging you cant pull the shoes out or the liner will fall through the bag. Some sort of retention would be ideal

    Great little bag

    Bought this bag for work and it’s exactly what I needed. Not too big, not too small. Just right for what I needed. Great construction with numerous pockets.
