Tuff-Thread is heavy duty and unbelievably lightweight. Made with RipStop fabric, this shirt won’t fray, it won’t rip, but it will live to fight day after day in the most extreme conditions. It’s the same weight as our Original shirts, giving you the durability you need without any extra weight. So whether you’re busting through brush, shouldering stacks of lumber, or elbow deep under the hood, the ultimate performance shirt is feather light and tough as nails.
