Men's First Lite Straightline Field Vest 18201-MOSFVDE The prairie pothole region of North America is known to duck hunters for its world class waterfowling. This landscape is very flat with rich soil, ideal for growing a buffet of crops that annually support over half of the hemisphere’s waterfowl migration. However, the lack of geological features makes the region especially prone to storms and ripping straight line winds. Agriculture + high winds are two optimal ingredients for a successful waterfowl hunt, so long as you have the right gear. Inspired by the harsh hunting conditions of the Dakotas, the Straightline Field Vest is 100% windproof, highly water resistant, and sets a new industry standard for soft shell durability. This style wears in, not out. Go Farther, Stay Longer.
