THE #1 ORGANIZED GYM DUFFEL

Don’t just manage your day. Master it. We don’t organize for a sense of calm. We organize to dominate the day.

Your gear, your grind, your greatness.

FAQS

Other than aesthetic differences, here are some of the ways organization differs between duffel models.

- The CONQUER Duffel is more structured. It’ll stand up on its own without any dividers inside. If you’re after a more sturdy duffel, the CONQUER is for you. If you’re after a collapsable, more flexible duffel that’ll pack away easier, the CORE Duffel is for you.

- The CONQUER Duffel dividers are more solid and click in place with magnets. The CORE Duffel concertina-style dividers are more flexible. Ideal for flat packing away.

- The CORE Duffel features more streamlined external pockets. Whereas the CONQUER Duffel has more chunkier 3D pockets, ideal for packing more quick access items.

- Shoe storage differs between bags. If using the internal dividers with the CORE Duffel, you’ll loose the ability to maximise the shoe compartment. While the CONQUER Duffel’s dividers are built so that the shoe compartment space is fully maximised while dividers are in use. The added structure also prevents shoes from being crushed underneath.

- The CONQUER Duffel internal dividers has 6 organizational zones (+ shoe compartment). The CORE Duffel dividers allow for a maximum of 4 zones. 


- The CORE Duffel features our unique external weightlifting belt attachment.

Overall, If you’re looking for an all round gym bag and prioritize having external lifting belt storage, the CORE Duffel is best suited. If you’re after a duffel that’s an absolute organizational beast, the CONQUER Duffel is your best match.

    A bag so good everyone asks me about it

    The best overall review I can give of the 40L duffel is that multiple people at my gym ask me about it. Once I have it open and the dividers exposed, it's clear that this bag is intelligently and purposefully designed for functionality. And that it is. Best part of the bag is that it obviates two other smaller bags I had been carrying along in addition to my main flimsy normal dym duffel. No contest when it comes to choosing a KNKG bag over a traditional one. Love it! 😍

    Best Gym Bag on the Planet!!!

    I read about this bag in Arnold's Pump Up Club daily newsletter and was intrigued. I am someone who needs compartmentalization as it helps me stay motivated to hit the gym when my bag is ready. It was more expensive than I had ever spent on a gym bag but it's worth every penny. It's like a traveling locker the modules fit right into a thin gym locker! The shoe compartment and sweaty gear compartment are great even for a size 13 and it's really durable. Very happy with my purchase!

    Greatest gym bag

    This is the best gym bag I’ve ever owned. The quality is through the roof and the durability of this bag is second to none. Everything is neatly organized and easy to assemble/disassemble to meet every one of your needs.

    Only downside is I wish I would have bought the one slightly larger than this one.

CONQUER Duffel — The Most Organized Gym Duffel with Modular Dividers

The CONQUER Duffel takes everything you expect from the toughest gym bags in the game and levels it up with built-in customizable modular dividers, rigid structure, and uncompromised shoe storage. Built for athletes, bodybuilders, powerlifters and serious gym-goers who demand order, it’s the duffel designed to keep every piece of gear exactly where it belongs.

Organization, Without Compromise

The CONQUER Duffel uses removable, magnetic modular dividers to give you full control of your setup:

  • Create zones: Shoes, sleeves, chalk, clothes, and tech each get their own space.
  • Adapt fast: Add or remove dividers depending on your session.
  • No wasted space: Keep gear upright and organized for quick visibility.

Shoe Storage That Doesn’t Collapse

The CONQUER Duffel features a dedicated ventilated shoe compartment engineered to keep its shape. Unlike soft duffels where the shoe area folds into other sections, this design keeps your footwear separate without stealing room from your main compartment.

What Fits Inside

With a 40L capacity and rigid structure, the CONQUER Duffel is built for lifters and athletes who carry serious kit:

  • Rraining shoes (lifters / runners up to size 15)
  • Change of gym clothes + towel
  • Knee sleeves, wraps, straps, grips
  • Shaker bottle and water bottle (dual external holders)
  • Chalk container
  • Meal prep containers or supplements
  • Headphones, phone, wallet, and keys

Features & Organization

  • Magnetic modular divider system for customizable layouts
  • Structured build that stands upright, even when empty
  • Chunky 3D external pockets for quick access
  • Ventilated shoe compartment that won’t collapse into other zones
  • Rigid walls for maximum visibility and space efficiency

Materials & Build

  • 500D nylon body material (with PVC backing)
  • Ripstop nylon lining
  • Heavy-duty YKK zippers
  • Reinforced stitching and premium hardware

The Toughest Gym Duffel Quality

The CONQUER Duffel isn’t just built to organize — it’s built to last. Reinforced seams, abrasion-resistant fabrics, and premium hardware make it a structured workhorse that thrives under daily gym and travel use.
