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 (35L) 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 and its length.

The CORE35 (medium) duffel can fit a belt up to 6.3"/16cm wide and 45.7"/116cm long.
The CORE51 (large) duffel can fit a belt up to 6.7"/17cm wide and 45.7"/116cm long.

A lever belt can fit, but you should count the lever into your measurement.

The CORE35 (Medium) will fit size 10 shoes. The CORE51 (Large) will fit size 13 shoes. Larger shoe sizes will fit our PLUS Duffel.

Workouts are tough but these bags are tougher. Effortless to carry and palpably robust. This thing does it all and measures in at the perfect size.

Designed for serious lifters who crave serious organization.

    This Bag Didn’t Just Change My Gym Game It Changed My LIFE

    Listen up, fellow gym warriors, weekend lifters, and sweaty-sock-toting legends the KNKG Core Duffel Bag isn’t just a bag… it’s a revelation. I don’t know what kind of wizardry went into designing this masterpiece, but somewhere out there, a team of gym-loving geniuses gave birth to a duffel so divine it deserves its own protein powder flavor. KNKG Vanilla Divider Swirl anyone?

    Let’s start with the dividers sweet barbell of Bethlehem they actually work. No more playing gym bag Jenga with my clothes, shoes, deodorant, and that one banana I forgot was in there for three weeks. With these dividers, my shoes have a home. My shaker bottle has a condo. My wrist wraps live in a gated community. Everything is organized like a Navy SEAL’s sock drawer.

    Build quality? NASA could use this material to build moon bases. I’m convinced this bag could survive a bench press PR attempt gone wrong, a pre-workout spill, and a toddler with jam hands all in the same day. I could probably throw it out of a moving car and it would just land, unzip itself, and flex.

    The zippers? Smooth as my biceps after arm day. The size? It fits more gear than Batman’s utility belt. The aesthetics? I look like I’m on my way to either crush a deadlift or disarm a bomb and that’s exactly the vibe I want. But here’s the kicker… this bag made me early to the gym. EARLY. I was so excited to pack it the night before, I woke up at 5 AM just to admire how beautifully my resistance bands sat next to my towel. It’s like…
