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.

    Powerlifting and Organization

    Love how organized this bag is with the dividers. I don’t get confused anymore where I store my headphones, chalk etc. It’s great having a dedicated attachment to store my Inzer lever belt as well. My old gym bag is still working fine but the core duffel has been such a huge quality of life upgrade that I don’t regret buying it.

    Last Gym Bag You’ll Ever Buy

    I’ve been lifting regularly for a few years, but also done a few triathlons. As a new dad, time’s limited. So this thing is a life saver. Big enough to fit everything - straps, weight belt, shoes, etc. But deep enough for cycling shoes and helmet, etc. I basically keep anything I’d need in this thing and a change of clothes so I can make the most of whatever time I have. Recommend the dividers, but definitely not mandatory.

    Perfect for the grab and go

    When you need the bare essentials, this bag is perfect. It’s durable to throw in the back seat and grab for the gym. Packs just what you need and a little more. There’s always room for snacks!

    Core Duffel in spectacular Halley Stevensons waxed canvas

    Core Duffel 35l in Halley Stevensons Waxed Canvas is exceptional and this waxed canvas is rarely available in the bags community.The fit & finish and materials used is both outstanding and spectacular.

    After having done some research I chose the Camo colour (A Muted British camouflage colour) as it subdues the Military/Tactical look. The layout of the bag is extremely well thought out making it adaptable for a number different use scenarios (not just limited to gym duffel only) such as air travel, camping, road trip, holidays to name a few. This due to large number and variety types of pockets.

    The carry handles padded cover on my bag was received with a broken press-stud (photo attached) which I found loose in the packaging is the only blemish on an otherwise stellar Duffel. I am sure KNKG will reach out to me for a solution or fix.
