FAQS

The CORE Mini Duffel is specifically designed to fit the KNKG weight belt. We don’t recommend using it with other belt brands. If you’re using a different belt, we suggest upsizing to the MEDIUM or LARGE CORE Duffel instead.

No - we don't recommend the mini size for shoe storage. If you're packing shoes we recommend checking out the medium or large size duffel.

    Perfect bag for most of my workouts

    I had been looking around for a small duffel for the gym for the last couple of months and I randomly decided to look here again. I already own a King Kong duffel that I really liked but didn't need so much room anymore so when I found there was a 15L duffel from them I jumped on it immediately. It has just the right amount of space for what I need for 90% of my workouts (I only use my other one on days I do heavy cardio and need extra clothes) and is small enough to easily carry around with me in the gym. The zippers are really nice and I love all the compartments. I only wish there was a bottle sleeve on the outside because I'm worried about it exploding inside the main compartment, but otherwise the bag is perfect.

    Overdue

    I should have purchased this bag a long time ago. I have been going to a gym and competitions for many years and never spent the money for a nice gym bag. Instead, I suffered through losing equipment or not able to find it when I needed it. This bag is compact, sturdy, organized and I will never need to replace it due to its high quality. Highly recommend! I got the organizer too and have it organized with neoprene and towels in large compartment; grips, straps, wraps and headbands in middle; jump ropes and a clean set of clothes in last compartment. It also hold my size 12 lifters neatly while standing tall.
