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.

    My new favorite bag

    Comfortable on the back and Carrie’s everything I need.

    I wrap my belt around it just like the pictures and my shoes stay protected from everything.

    Awesome Backpack — Tons of Space and Super Comfortable

    I’ve been really impressed with the CORE Backpack Large 33L. It has a ton of space without feeling bulky, and it’s been perfect for everyday use, work, travel, and hauling all the random stuff I end up carrying around. The layout is great, with enough compartments to keep everything organized instead of just turning into one giant black hole.

    It’s also really comfortable to wear, even when it’s loaded up. The straps feel solid, the bag seems well made, and overall it just feels like a quality backpack that can take some use. If you need something roomy, practical, and good-looking, this one is absolutely worth it

    Got the bigger one this time!

    Second time getting a KNKG bag, it’s been super durable and this one is larger. I can fit both my squat shoes and deadlift flats in the shoe compartment (size 9.5) and there’s still plenty of room.
