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.

    Such a nice looking bag, holds its shape, and fits my daily gym essentials perfectly. It won’t really hold a change of clothes, but if you’re like me and you just change at home, then it doesn’t matter. I carry the gym reapers dip belt, ekkovision d ring cuff straps, warmup bands (not pictured), and a hydroflask and it all fits perfectly. I love this thing and if I didn’t already have a large bag for if I need to change, I would buy a bigger one as well. Even the zipper feels solid and heavy duty.

    Self waxed

    I got this in green and waxed it myself to match a goruck heritage for daily use to the gym. Came out very solid and like it. The bag is a great daily gym bag. I with it was a liter or two bigger for shoes and gym equipment. But it is great size for daily trips with lots of compartments.
