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 Jacket is 100% windproof, highly water resistant, and sets a new industry standard for soft shell durability. The Straightline product family also includes a vest configuration. Check out the Straightline Field Vest here This style wears in, not out. Go Farther, Stay Longer.
