Another bright idea from Arborwear. What is the biggest problem with safety colored clothing? It gets as dirty as your work after a short time, right? Well, get the best combination of longevity and visibility with the 2-Tone Tech TSHERRILLtree. They are dark colored where a shirt gets dirtiest and bright colored to keep you visible in a tree or on the jobsite. Made from the same 15% cotton/85% Polyester blend DriRelease with the odor neutralizer, FreshGuard.
