Propper Poly/Cotton Twill 27/P Flyers Coveralls are designed for aircrew and maintenance personnel who don't require FR protection. Crafted from 5.2 oz 65% polyester and 35% cotton twill, this breathable coverall is fade and wrinkle-resistant. It features a two-way zipper front with a convenient cloth pull. Reinforced shoulders improve durability, while a bi-swing back offers on-the-job flexibility. With multiple pockets, including a knife pocket in the left thigh, carrying essential flight gear and tools is a breeze.
