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.

    KNKG is the best

    This is the most organized I have been in a long time. The bag has many pockets outside and inside. I carry two pairs of shoes, lifting belt, wrist bands, knee sleeve (2 pair), grips (3), water bottle. I also purchased the dividers for this bag, they our the best to keep everything organized. So glad I finally purchased.

    Well Done

    Was looking for a bag that would fit by size 13 brunt work boots. This is the only bag that would fit them that was also well organized. Great product and love the layout and feel. The belt storage is also really cool

    Great bag, incredible value

    I bought the duffel mini, getting turned on to the bag and the company via my membership in the Pump Club. I really dig how the recommendations the PC passes along on everything is rooted in research and proven metrics. Bought the bag as a way to reduce friction to working out — a packed bag is one less reason to talk myself out of a workout.

    This bag has surpassed my expectations. I’m 27 weeks into my association with the Pump Club, so my needs at this point are pretty minimal: shoes, workout clothes, water bottle, and pockets to stash personal items. This bag has it all, thoughtfully designed with top flight, heavy duty material, from the nylon to the strapping to the zippers. I’d highly recommend any KNKG bag to anyone.

    Amazing bag

    I absolutely love this gym bag! It has so much room without feeling bulky, and I can easily fit my shoes, clothes, water bottle, toiletries, and still have space left over. The compartments make it easy to stay organized, and everything has its place.

    It feels sturdy and well-made, and the straps are comfortable even when the bag is full. Perfect for the gym, travel, or even an overnight trip. Highly recommend if you need something spacious and reliable!
