Given the quality of golf wind jackets we have tested at Golf Monthly, we definitely think windbreakers are worth it. The best models protect from the wind and elements well, helping you stay warm in your core and arms. They also stretch well so you can swing unimpeded and the top models are comfortable as well so not only do they work on the course, but elsewhere too, on walks, hiking, and so on. Lightness, versatility, style and value are also key elements we have noticed in the best models so yes they are worth it.
