  • 13” internal laptop sleeve.
  • Sealed internal shoe compartment.
  • Dual bottle pockets.

This version of the CORE Duffel features a waxed canvas body - an ultra-durable cotton canvas impregnated with wax for water resistance. Waxed canvas develops a rugged, lived-in look over time, with marks and creases that add to its character. It delivers the same proven longevity as our ballistic materials, with a vintage feel that gets better the harder you use it.

This CORE Duffel is made from:
• Water-resistant Scottish waxed canvas from Halley Stevenson (cotton, waxed finish)
• Genuine Cow leather logo patch & zipper pulls
• YKK zippers
• Powder-coated steel buckles
• Ripstop nylon lining
• Nylon webbing

NOT JUST DURABLE - DEPENDABLE

Built with a water-resistant waxed canvas shell, this limited edition CORE Duffel is crafted for those who aren't afraid to roll up their sleeves and get the work done. Every crease, mark, and scuff tells the story of work put in and limits pushed. No shortcuts. No excuses. Just a bag that shows up like you do.

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.

    Sturdiest bag I have ever owned

    I am hard on bags. I have a timbuk2 bag that I have loved, but I have outgrown it. I could not use a backpack, so I needed a tough roomy duffle. The Core duffel more than delivered.
