BUILT TO GO THE DISTANCE

Waxed canvas isn’t just for looks. It’s a proven material trusted for over a century. Water-resistant, tough by nature, and built to age with character. This isn’t a trend piece. It’s a workhorse built for the grind.

PACKAGED WITH PURPOSE

This isn't your average unboxing. Our limited edition Waxed Canvas Collection comes packaged in a premium keepsake box - making it the perfect gift or collector’s piece. For a limited time only, each set includes a genuine leather wallet and keyring.

FAQS

The main difference is the unique external weightlifting belt attachment - letting you carry your belt on the outside without sacrificing internal space. This version also features a 35L capacity and a reworked layout for streamlined storage. It's built from waxed canvas, a water-resistant cotton material that develops a rugged, vintage look with use - making it as tough as it is timeless.

Measure the widest point of your belt and its length. The CORE35 (medium) duffel can fit a belt up to 6.3"/16cm wide and 45.7"/116cm long.

A lever belt can fit, but you should count the lever into your measurement.

The CORE35 (Medium) will fit size 10 shoes.

    Hi quality Duffel

    I have to say this is a near perfect Duffel bag!!! The company is top notch with their customer service. I wanted to exchange something and they were more than accommodating in assisting me in the process. The quality of the bag is top notch. This bag will no doubt be the last one I purchase as I believe it will stand the test of time.

    Just 2 suggestions in design. First a solid handle at one end of the bad to make it convenient to pull out of airplane carrying on bin or just to grab and hold it vertical and second use the larger zippers on the side storage pockets instead of the small zippers which can be difficult to close and open around the corners.

    Seriously a great bad!!!

    Exceeded my expectations!!

    Best gym bag I have ever owned (and I’ve had many). The bag’s design and build are excellent. Not only is it easy to access items in the bag while working out, but it doesn’t fall over onto the floor like my backpacks did. I only wish I had this bag years ago. Well done!!👍

    Best bag ever

    This bag came in handy more than any other one. Its great for throwing overnight things in or just loading up items for the day. The wax coat makes it look amazing and it is 100% waterproof. I have three of these bags and backpacks and i wont buy another bag other thatn KNKG
