When you think about it, a quality gym bag can be the silent hero to your workout regimen. Effortlessly keeping your shoes, accessories and other essentials secure for transport, these vessels can really take the stress out of training — which makes mustering up the motivation to hit the weight room or studio much more achievable.
There’s a variety of styles to choose from when it comes to gym bags, from the sleek and elegant to the roomy and durable. One such tote that’s caught our eye as of late has been the King Kong Core35 Duffel. With a tough canvas exterior, well-designed pockets and unique features for accommodating your go-to gym gear, this bag looks to be the answer to all your fitness inquiries. But to reap the benefits of all this innovation, you need to pay for it — the Core35 Duffel is not cheap when you compare it to other duffels you’d find at your local sporting goods store.
To see if the hype is worth the higher price tag, I swapped out my normal gym bag and loaded up the Core35 for my routine trips to the gym. I typically carry an abundance of lifting accessories like a belt, wrist wraps, lifting straps, supplements and more, so I was sure that my typical inventory would be sufficient in testing this bag’s capabilities. I also made note of how easily I could carry this bag across the gym during training, as well as its storage capabilities in a typical gym locker.
Here’s what you can expect when loading up with the King Kong Core35 Duffel.
