The Prairie Twill Collection by Flying R Ranchwear is new and improved! This is a tough shirt with just enough heft to make it a great layer. We've added a little extra length to the fronts and back too, so it can be worn over a shirt. Available in a large range of sizes, up to 4XLT (20.5x38). 65% Poly/35% Cotton, 5.5 oz. twill, Made in the USA.
