Wool is fleece from sheep. Its crimpy fibers create millions of air pockets, making it a natural insulator. The long, exterior antistatic fibers repel water and soil while the shorter, interior fibers absorb moisture vapor up to 30% of the weight of wool before it feels damp. And wool retains 97% of its strength when it's wet!
Use them specifically for Steelhead Fishing. Large enough too keep hands warm and great for tailing fish
