After testing five popular gym bags and speaking with the manufacturers, I'm ready to share my findings. The best powerlifting gym bag is the KNKG (King Kong) Core Duffel.
While this bag wasn’t initially marketed toward powerlifters (originally it was for Crossfitters and Strongmen), it has everything that a powerlifter needs in a gym bag:
- It has a dedicated external belt attachment (essential for saving internal space).
- It’s wide enough to fit up to two pairs of shoes (squat and deadlift shoes).
- The canvas material is ultra-durable, suitable for both the gym and the platform at a meet.

1. KNKG Core 35L Duffel – Best Overall Powerlifting Gym Bag
The KNKG (King Kong) Core 35L Duffel is my top recommendation for a powerlifting gym bag because it was built from the ground up to be a gym bag, and a gym bag only.
I chatted with Stefan on the phone not too long ago, the CEO of KNKG, and he told me the story of how by creating the bag he was trying to solve his own pain point of walking into the gym with a bag that just simply wouldn't hold all of his gym gear properly.
This brings me to the main feature that I love about this bag: The external belt attachment. Rather than trying to put your powerlifting belt inside the bag, you can wrap it around the bag, which saves a lot of other room for other items inside the actual main compartment.
I have a 10mm lever belt, and I thought the lever attachment wouldn't be able to fit into the side pouches, but I was wrong. It can definitely fit a standard-sized powerlifting belt.
And a quick note on that. If you respect the KNKG brand, you'll want to check out their new lifting belt. Here's where to get it. It's already got more than two dozen five-star ratings, and it's backed up by a material and workmanship warranty. Solid.
But back to this bag. It's a beast.
The Core 35L (and the larger Core 51L) has multiple compartments to store various big and small items including both your squat shoes and deadlift shoes. Not many bags I tested had enough room for both shoes. So for a ‘powerlifting-specific bag’, this was an excellent feature.
The bag is made of canvas fabric, which is extremely durable and can take a beating. I don’t know about you, but I’m pretty hard on my gym bags. I’m tossing it around in the gym, throwing it in and out of my truck, and traveling with it to powerlifting meets. So durability is key.
Another thing about the canvas material is that it’s mostly waterproof, so they’re pretty good at handling sweaty gear while staying easy to wash and clean! That makes it good for everyday use, even for a serious lifter.
Also, if you're not using the belt pouch, I slid my sweaty clothes, including my knee sleeves inside the outer compartment after my workout, which was great for not getting any of the gear I wanted to stay dry inside my bag (wraps, straps, etc.).
The last thing I’ll say is that you won’t be disappointed with the internal capacity. You’ll be able to fit everything from sleeves to wraps, and everything in between, inside the bag without feeling like you’re shoving or cramming it together.
Pros
- Stores the belt on the outside to save internal space
- Huge internal capacity with multiple waterproof compartments
- Fits 2 pairs of shoes (Squat & Deadlift)
- Extremely durable canvas construction
Cons
- A bit pricey but will last for a long time
2. WolfPak 35L Backpack – Best Backpack Option
If you prefer a backpack over a duffel, the WolfPak has completely taken over the powerlifting world in 2026.
Walk into any serious powerlifting gym, and you will see these rectangular tactical backpacks everywhere. Why? Because of the front belt loop system. Similar to the KNKG duffel, WolfPak allows you to strap your lever belt directly to the front of the backpack.
The “Traditional” 35L size is perfect for most lifters. It features a rigid, boxy design that stands up on its own (great for locker rooms) and opens up fully like a suitcase (Clamshell opening), making it easy to pack your knee sleeves and singlet.
It also features a Velcro space on the front for patches, allowing you to customize it with your federation or club patches, which is a fun touch for competitors.
Pros
- Clamshell Opening: Opens flat for easy packing.
- Belt Loop: Securely holds lever belts on the outside.
- Style: Highly customizable with patches.
Cons
- Material is polyester (slightly less premium feel than KNKG's nylon).
3. Nexpak Gear Bag – Best Budget Tactical Option
If you love the “tactical” look but don't want to spend over $100 on a WolfPak or KNKG bag, the Nexpak is a solid budget alternative.
This tactical duffle bag comes with tons of designs from solid colors to military camo. It has a total internal capacity of 42 liters, which is actually larger than the KNKG Core 35L.
It features the MOLLE system on the outside, so if you are handy with clips and carabiners, you can rig up your own belt attachment system. However, bear in mind that it is made of cheaper polyester. It won't last a lifetime like the premium picks, but for the price of a tub of protein, it does the job.
Pros
- Extremely affordable.
- Massive 42L capacity.
- Tactical aesthetic fits the powerlifting vibe.
Cons
- Zippers and material are lower quality.
- No dedicated belt strap (you have to DIY).
4. MIER Duffel Backpack – Best for Cyclists/Commuters
Wearing a cross-shoulder duffle bag to a gym is usually the most convenient way for balance. However, if you bike to the gym, a heavy duffel sliding off your shoulder is a nightmare.
The MEIR convertible duffel solves this. It comes with detachable straps that convert it from a standard duffel bag into a backpack instantly.
It is waterproof (great for rain) and features a dedicated shoe compartment. While it lacks a specific lifting belt holder, its versatility makes it the best choice for the urban athlete.
5. KNKG Heritage Leather Duffel – Best Premium Bag
If you are a serious lifter who wants to look professional, the KNKG Heritage Leather Bag is the Rolls Royce of gym bags.
It’s manufactured using full-grain American leather that is highly durable. Unlike cheap leather bags that scuff easily, this one develops a nice patina over time.
It features the same magnetic/zipper functionality as the Core line but in a package that looks just as good in an airport lounge as it does in a squat rack. It’s expensive, but it makes a statement.
Why Powerlifters Need A Special Gym Bag?
Here are some of the reasons why a powerlifter needs a special gym bag:
Belt Storage is The #1 Issue
A powerlifting belt is rigid, large, and awkward. If you put it inside a normal bag, it acts like a giant spring, taking up all the room. Powerlifting-specific bags (like KNKG and WolfPak) move the belt to the outside of the bag, which is the single most important feature to look for.
Multiple Pairs of Shoes
Serious lifters carry Squat Shoes (heeled) and Deadlift Slippers (flat). That is two pairs of footwear plus the shoes you wore to the gym. Standard bags usually only have one shoe pocket. You need a bag with massive capacity or dual shoe pockets.
Wrap Up
If you are tired of carrying your belt in your hand or having it crush your snacks inside your bag, it's time to upgrade.
The KNKG Core Duffel is my recommendation for the best overall duffel due to its durability and sleeve-style belt attachment.
If you prefer a backpack, the WolfPak is the trendy and functional choice that has taken the industry by storm.
