A TIMELESS ATHLETIC BAG THAT OFFERS THE SAME PERFORMANCE ON DAY ONE THOUSAND AS IT DID ON DAY ONE.

My first memories of training were of leather speed balls and well-worn heavy bags. These pieces had hung in the gym since the turn of the previous century and yet were still the toughest things in the gym. Twenty-five years later, I still find inspiration in the smell of leather and the feel of an old leather heavy bag. I want to recreate that feeling, that gym atmosphere before the time of elliptical trainers, smartwatches, and large, clunky treadmills.

Leather yields strength and longevity. It's timeless and holds a sense of heritage. This is a bag I'm proud to carry both inside and outside the gym. One that will wear in over time, rather than wear out. A bag that will only get better with age, developing a unique patina as is it moulds to me and my training.

- Stefan, KNKG Founder

FAQ'S

Any size sneakers, runners or lifters will fit inside the shoe bag. We don't recommend storing army boots in the shoe bag.

We made a few key updates! Most notably, we added a smaller duffel size. Based on your feedback, we also upgraded the materials for both the duffel and the internal shoe compartment—making everything lighter and more comfortable to carry.

    Best purchase I’ve made

    Was in need of a new gym bag and found the perfect one at such an unbeatable price! Thought the 25L might be a bit small but it’s just enough space for what I need and the side water bottle pockets are so convenient. Fits perfectly in a locker too.

    The king of all bags

    I already have the PLUS duffel medium, and I was debating getting a smaller bag for when I don't need to lug as much stuff to the gym. This bag is perfect. It's the perfect size and also the nicest gym bag I have ever seen. It almost seems too nice to bring to the gym, but it has the durability that King Kong is known for. Also I bring two pairs of shoes to the gym (in addition to the ones I wear there), and the shoe bag fits both pairs - as well as my belt and other accessories. I'm not sure why I hesitated to get another bag, but I am definitely happy I got it.

    Gym Rat to Executive - this bag is phenomenal

    The Heritage Leather Duffel is a phenomenal value. Before purchasing this bag I could not find anything of this quality and versatility that could serve me both in the gym and traveling for business. It’s classy, heavy duty, and absolutely beautiful!! I feel like I splurged on a high-end bag without spending big bucks on it. I challenge anyone to find a better quality bag for the value. This is one purchase with ZERO buyers remorse… nothing beats it!!
