The 5.5 oz Women's Uniform shirt features the same lightweight, breathable, moisture wicking TECGEN® FR fabric, incorporated into a dress shirt designed for women. We have been confirming our features like an open collar, proportional pockets, left-hand buttoning, and a feminine silhouette with women in the industry. The result is a light weight woven women's shirt certified for 70E HRC2, and 2112-2012 flash fire. This shirt will also help you meet the new OSHA 1910.269 Utility regulations.
