There's tough. And then there's the Grindstone GTX Jacket. We made this so you can stay dry and keep working through the worst weather. It's the most durable GORE-TEX(R) rain gear we've ever engineered-even our lab testing machine couldn't break it. It's built to keep you dry through season after season of working your back 40, hauling lumber, tuning engines, and everything else it takes to get the job done. And unlike heavy canvas or waxed workwear, it's breathable so you won't get sweat-drenched. If you need to take on torrential rain and dawn-to-dark jobs, this is the jacket you'll reach for every time.
