Propper Poly Cotton Twill 27P Flyers Coverall - Durable, Practical Fit

In this review of the Propper Poly/Cotton 27/P Flight Suit, the bottom line is simple: it is an affordable, well-made non-FR coverall intended for air crew, maintenance staff, and uniformed personnel who need the look and pockets of a flight suit without flame-resistant protection. The biggest reason to buy is the durable, colorfast 5.2 oz poly/cotton twill that balances lightweight comfort with long wear, making it a sensible choice for daily uniform use or training environments where FR is not required.

Key Features

• Sewn to spec: Built to the mil-spec YACL-WP PD 99-01 R pattern for authentic flight suit details and construction quality that mirrors Propper's Nomex style.
• Durable fabric: The 65% polyester/35% cotton 5.2 oz twill is colorfast and resists wrinkles and shrinkage, so it stays presentable after repeated wear and laundering.
• Pocket layout: Six primary zipper pockets plus a left shoulder hook-and-loop pocket and a left inner-thigh knife pocket offer plentiful storage for tools and small gear.
• Zippered leg openings: Leg zippers make it easier to don or remove the suit and allow it to be worn over boots for practical use in the field.
• Fit adjustments: Alpha sizing, a pleated bi-swing back and hook-and-loop adjustable waist belt give a generous, mobile fit suitable for layered uniforms or movement-intensive tasks.

Who It's For

The suit is best for non-FR use cases: maintenance crews, ground support, law enforcement support staff, public safety teams, and training or display units that want authentic flight-suit styling without the cost of Nomex. It is also practical for commercial pilots or technicians who need durable pockets and a uniform appearance.

Those who need certified flame-resistant protection, or who require a close-fitted, tailored cut should look elsewhere; this coverall is sized in alpha measurements with a generous fit and may feel baggy in the legs or long in the torso for some wearers.

• Durable, lightweight poly/cotton twill that holds color and resists shrinking.
• Authentic flight suit construction sewn to mil-spec pattern for reliable detailing.
