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.

    Great product and customer support

    Ordered a gym bag and within a couple weeks I noticed a defective thread on one of the velcro straps. Reached out to this company and they sent me a new one right away! These bags are solid! I take mine to the gym everyday and then throw it in my work truck and go to work. It gets moved around the gym multiple times and bounces around my work truck all day. This thing will last many years!

    Large Duffel

    I ordered the medium duffel and it wasn’t quite big enough. The customer service was outstanding! They got me a return label and I ordered the large. It’s the perfect size for me. Holds shoes, a towel, crocs for the shower, a change of clothes, my jump rope, my grips, and some preworkout. The side pockets for my water and shaker bottle are perfect. Worth the investment!

    No buyer's remorse here - LOVE my CORE

    Absolutely love my new duffel. I hee-haw'd for a bit because it wasn't an inexpensive investment, but I can honestly say I didn't have a moment of buyer's remorse when I unpacked it. The quality is top-notch and I can see why the offer a lifetime guarantee ... nothing is going to get to this bad boy!
