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.

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

    Great for carrying all my gear and keeping it separate.

    Able to keep gear separated before and after workouts. I would recommend it for light travel and the gym.

    Mixed Feelings

    Quality of bag materials is solid. Functionality of bag is not great. I like the open top access but the amount of room in the bag is drastically reduced when I use the shoe compartment which only has a pair of slides for the shower in it. Front pockets are slim/tight so you really fit much in them except a pair of lifting straps. Belt storage feature is great in concept but the Velcro makes it a challenge to get your belt in and out. Not really worth the $$$.

    Tore after a few uses

    The shoe compartment to Hoban after a few uses. Reached out to them, they said they would get back to me, haven’t gotten back to me. It’s been a handful of days. This is just a current review.

    Sleek, Smart, and Built to Last

    The KNKG Core Backpack is a minimalist's dream — clean design, durable materials, and just the right amount of storage. It fits my laptop perfectly, has smart compartments, and feels comfortable even on long days. Great for work, travel, or everyday use. Simple, stylish, and reliable.
