These might just be the toughest trousers you’ll ever own—and that’s no small claim. Built from an ultra-heavyweight 580gsm 100% cotton twill, they’re engineered to take on years of hard use while only looking better with age. Whether you’re on site, in the workshop, or just want a pair of trousers that can handle anything, these deliver uncompromising durability and timeless style.

Reinforced with a double-knee panel, triple-stitched seams, and a YKK metal zipper, every detail is designed with longevity in mind. Solid INR hardware and a custom shank button waistband ensure a secure fit, while the traditional five-pocket pattern and twill-reinforced rear pockets add everyday practicality.

From the heavy cotton twill to the meticulous construction, these trousers are built for men who demand the most from their gear. Tough, dependable, and made to last—this is workwear that doesn’t back down.
