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.

Love the variety of pockets to store items to use at the gym. The shoe storage is my favorite. But the number of different size pockets is quite smart to store many different types of needed things. I normally wouldn’t buy a duffel bag for the gym/fitness center but I’m glad I did. Really like it…

I never leave reviews, but this is seriously the best gym bag I'll ever own. It's high quality, great materials, and it's built to last. I'm very glad I made this purchase and I would buy again.

This is hands-down, the best gym bag my husband has ever owned. I just bought him a second one because he wanted to have two bags packed for different places. It’s extremely functional and I like that there’s no big logo advertising for Nike or Adidas or other places like that. It’s adorable, functional and aesthetically pleasing.

I wanted a bag with some structure that would hold its shape. This does so well, and the zippers feel very durable. I like how the compartments are laid out as well. Overall, quality bag. The two shoe compartments are a plus.

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
