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.

    Best Gym Bag

    KNKG has the best bags. This is my second and I use both for the gym. Durable, and there is a place for everything and easy to find.

    Perfect Gym Bag

    This has become my perfect gym bag. Easily carries whatever I need for that day, even on leg day when I carry my lever belt, knee sleeves, shoes, and more. Enough space and structure in the main compartment and the smaller area are perfect for the other things you need (air pods, lock, keys and wallet, tape). So glad I pulled the trigger on this bag. Worth every penny.

    Good bag, slight QC issue

    Works great for what I need it for! Only giving 4 stars because one of the zipper pulls came loose upon arrival. Otherwise, no complaints.

    CORE Backpack Waxed Canvas Mini 13L
    I recommend this product
    Rated 5 out of 5 stars
    Compact and stylish

    Originally bought this for the gym, but the moment I opened the box I decided it was far too nice for that. It’s beautifully made, the material feels rugged but still looks refined, and the smaller size suits me really well. Easy 5/5 one sexy bag. The only downside is that the material(waxed canvas) seems to pick up dust fairly easily, but that’s more about the fabric than the bag itself.
