Propper Poly Cotton Twill 27/P Flyers Coverall - Durable Non-FR

In this review of the Propper Poly/Cotton 27/P Flight Suit the bottom line is simple: it is a practical, cost-effective coverall for air crew, maintenance staff, and uniformed personnel who do not need flame-resistant clothing. The suit is sewn to mil-spec design and delivers a familiar flight-suit layout with multiple pockets and a generous alpha sizing system, making it easy to move in and wear over boots; the single biggest reason to buy is durable, lightweight twill material that balances comfort with serviceable longevity.

Key Features

• Sewn to spec: Constructed to the mil-spec YACL-WP PD 99-01 R pattern so users get the same functional design and pocket layout as professional flight suits.
• Durable fabric: The 5.2 oz 65/35 polyester/cotton twill is lightweight yet colorfast, wrinkle resistant, and resists shrinkage for easier care and longer wearable life.
• Multiple pockets: Six primary zippered pockets plus shoulder and inner-thigh accessory pockets give plenty of storage and options for tools or small gear.
• Zippered leg openings: Leg zips make it easier to put on and take off the coverall and allow wearing the suit untucked over flight boots.
• Fit and mobility: Alpha sizing with a pleated bi-swing back and adjustable hook-and-loop waist belt provides a roomy fit and freedom of upper-body motion.

Who It's For

This Propper coverall is best for aviation support crews, maintenance personnel, law enforcement or public safety staff who need a tactical-style, non-FR flight suit with practical pockets and easy-care fabric. It also suits commercial pilots and ground crews who want military-style fit and features without flame-resistant material.

Those who need certified flame-resistant protection should look elsewhere, and anyone seeking a trim, fashion-fit coverall may find the alpha sizing intentionally generous - some users report baggier legs and a longer torso compared with fitted workwear.

Pros & Cons

Pros

• Durable, lightweight 65/35 poly/cotton twill that is colorfast and low maintenance.

• Zippered leg openings for easy donning and wearing over boots.

Cons
