I am delivering glass, but recently the installation and clothes of work in the warehouse became annoying and admission with short sleeve work clothes was prohibited. However, air conditioning is also beneficial if it is only work in the field, but the delivery destination is in the hot weather. I wear it when I enter the entrance and take it out when I go out. The fabric is also thick and perfect for loading glass. The difficulty is high priced because it is a top-notch trussco. Though I bought at the same time was a quarter price, it was ultra thin.
