Take a look inside a pair of Patagonia waders: You’ll see a unique serial number that tracks every detail in the production of that pair. It’s the work of Patagonia’s Wader Task Force—a group of people, from chemical engineers and textile developers to designers and field testers, all dedicated to one task: building the best waders. Tracking every detail, every time is just part of what they do. The Wader Task Force is an ongoing process of inquiry, a feedback loop that takes everything we learn from testing, design and production and applies it to the development of the next generation of waders.
