The technology behind VOORMI's SURFACE HARDENED Woven Wool is so unique that with this process they are able to create any garment from lightweight fishing/lodge wear (Lodge Fishing Shirt) to a burly outer layer (AN/FO Jacket) designed for the men and women who spend their lives working in the outdoors. This 4-way stretch fabric construction is built from burly 21.5-micron wool, reinforced with high-performance nylon and finished with a durable water repellent (DWR) treatment. Summer on the river or winter in the mountains, this Holy Grail of apparel technology, from lightweight fishing shirts to heavy duty performance work wear, is the answer to constant comfort and lasting performance.
