TRADITIONAL WAXED CANVAS GYM DUFFEL

WAXED. WEATHERED. UNCOMPROMISING.

The unique external belt attachment keeps your lifting belt secure on the outside, freeing up valuable space inside the bag. With smart storage throughout, it’s made to back you through training, travel, and everything in between.

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

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.

    So many things I buy online, sight unseen fall incredibly short. This bag is amazing… I changed out the zippers with custom 550 cord (the originals were too dangly), but the waxed canvas - probably great in the gym - is even better under airline seats.

    Quality craftsmanship is second to none - only thing I’d have added is a lanyard for keys, or at least just a metal anchor inside to attach a clip with keys too. A true travel version of this bag might additionally include a pen sleeve… the pocket on the left side is perfect for a large phone, and the iPad sleeve is perfect - I carry an additional 13” laptop for work that fits next to it outside the sleeve.

    Youd never believe this bag is 15L - bigger and more useful than you can imagine.
