15oz Martexin #10 Structural Duck Canvas 

The structural chassis is cut from genuine Martexin original waxed #10 duck canvas by Fairfield Textiles. It acts as a heavy-duty armor shield against sharp steel edges and grease, repelling water while developing a rich patina over a lifetime at the workbench.

10.10oz Martexin Army Duck Pockets 

We use a slightly lighter, highly durable 10.10oz army duck canvas for the internal pocket matrix. This specific weight configuration gives you the perfect amount of flex to slide tools home cleanly without choking adjacent slots or binding the fabric.

Solid Antique Brass Hardware 

No plastic buckles. No cheap plating. Every fastener and collar button is solid antique brass sourced from Buckleguy, ensuring rust-free, unbreakable security under tension.

Sarabond Size 92 Bonded Polyester Thread

Every seam is locked down with heavy-duty, UV-resistant bonded polyester thread. It resists severe workspace abrasion, will not rot when exposed to moisture, and ensures your critical load-bearing points never experience pocket blowout under high tension.
