PACK FOR MOVEMENT
The best traditional gym bag for anyone who wants to bring fresh clothes to a workout and take sweaty clothes home again, without your gear resembling a fragrant swamp. It's tough enough to last a limetime, and its six compartments kept us organized.
GEAR UP FOR IMPROVEMENT

I needed a new gym bag. What I didn’t expect was to immediately retire every other duffle I own. As a before-work gym goer, I pack a lot—shower stuff, a full change of clothes, and gym gear like straps and knee sleeves. I assumed I’d still be cramming things in every morning. Turns out, this bag handles it just fine.
I did buy the packing cubes made for the bag, and they help a lot. I have the medium size, so only about two-thirds of the cubes actually fit, which feels fair. The ones that do fit keep everything organized and save me from digging around half asleep wondering where my deodorant went.
Even after all that, I can still throw in my extra-large sweatshirt and sweatpants post-workout without a problem. It’s roomy, well thought out, and makes my mornings easier instead of more chaotic. If you’re looking for a gym bag that actually keeps up with how much you bring to the gym, this one does the job.

Big and spacious to fit all my gym gear with an abundance of pockets. The material feels high quality.

I've been using this bag for a few weeks and love it. There is plenty of space for my sneakers, a change of cloths, bathroom bag and random gear. The two shoe compartments are large and I often use one for my dirty gym clothes. I highly recommend it.

I bought this bag as a gift for my fiancé and she absolutely loves it. She uses it every day for HIIT and weightlifting. She used to have to use a bag for each.

I was using a smaller generic bag for the last couple years and was always struggling to find space for all my gym gear. This Christmas I received some new stuff to up my CrossFit game and I knew I needed a new bag. I did a bunch of research and honestly nothing came close to the value you got from KNKG. It’s a high quality product that came in great color options. The main thing that sold me was the double shoe compartments. I feel so organized now! Looking back I can’t believe it took my so long to make the switch. 100% recommend and will be buying other products in the future.
PLUS Duffel — The Original KNKG Gym Bag with Unmatched Shoe Storage
The PLUS Duffel is the bag that put KNKG (then King Kong Apparel) on the map. Originally designed for CrossFit, it’s a traditional gym bag elevated with smarter organization, reinforced durability, and the shoe storage system that changed how athletes pack for training.
Why the PLUS Duffel Stands Out
The PLUS is made for everyday athletes who need smarter storage. With dedicated compartments, reinforced construction, and dedicated shoe zones, this is the bag built to handle every training day.
Shoe Storage by Size
- Small (33L): Holds 1 pair of shoes up to size 15.
- Medium (45L): Fits 2 pairs, even size 15+ boots.
- Large (63L): Fits 2 pairs of lifters, sneakers, or boots.
The PLUS Duffel shoe zone is ventilated to keep the inside fresh and separated from clean gear.
Pockets & Organization
- Dedicated shoe zones
- Spacious main compartment for clothing, towel, and bulk gear
- Side pockets for wraps, straps, and smaller items
- Quick access valuables pockets for wallet, phone, and keys
Materials & Build
- 1000D nylon body material
- Ripstop nylon lining
- Heavy-duty YKK zippers
- Steel buckles
- Hypalon trims for reinforcement
The Toughest Gym Bag Quality
The PLUS Duffel was built to last from the very beginning. Reinforced stitching, abrasion-resistant nylon, and steel hardware means it can take years of daily training and travel — and still hold up like day one.
Why Choose the PLUS Duffel?
- Classic gym bag design with smarter compartments
- Dedicated shoe zones sized for lifters, runners, and boots
- Multiple capacities: 33L, 45L, and 63L
- Originally designed for CrossFit, trusted by athletes worldwide
- Proven quality: the bag that started it all
