BUZZ RICKSONS
BUZZ RICKSONS / M-51 Field Trousers
Field trousers made using the reverse side of cotton sateen fabric adopted by the U.S. Army in 1951.
They were developed as part of the M-51 series setup layering system, with a background as combat wear for cold-weather environments.
Worn on their own, they function as standard all-season trousers. In cold regions, they were designed to be layered over wool field trousers.
Each item was created to trap body heat while blocking out the outside air.

BUZZ RICKSONS
Founded in 1993, BUZZ RICKSONS is a brand that pursues the history and pride of flight jackets. Its reproduction work is based on the military specifications of the time, with meticulous attention paid to every detail, from yarn spinning and weaving to fabric materials, military parts, and the overall form. Each piece is made with craftsmanship to recreate the appeal of vintage flight jackets.


Faithfully Recreating the Original Cold-Weather Design
The fabric is made from what is commonly known as back satin, using cotton sateen with the reverse side facing outward—just like the U.S. Army field trousers from 1951.
This material combines warmth and durability, delivering reliable performance designed for wear in cold climates.
The texture of the surface and the smoothness of the reverse side convey the distinctive atmosphere of military clothing from the era, while also ensuring modern ease of wear. The historical value found in the details creates a style with a character all its own.
Designed with Practicality in Mind
The waist features a zip fly closure, finished with a TALON zipper for an authentic reproduction down to the smallest details.
In addition to belt loops and adjusters, the design faithfully recreates the original-era detail of suspender buttons.
The interior cord loops are designed to hold the metal hooks at the ends of suspenders, faithfully reproducing the functional details of the original construction.
The cargo pockets are equipped with tourniquet cords. As the cords hang down, they add movement and become an accent in styling.
The knee area uses a three-dimensional structure that allows easy movement without restriction.
The hems are equipped with drawcords, allowing you to change the silhouette and adjust the fit to help block wind from entering.
These detail-rich trousers combine practical functionality with authentic historical design.
Recreating the Style of Military Clothing from the Era
The silhouette is a loose fit designed with cold-weather wear in mind. Made to trap body heat and block outside air, it faithfully recreates the style of military clothing from the time.

Staff Fitting Comments
| ●Staff Height / Weight: 165cm / 64kg Worn Size: S Body Type: Slim Thigh Area: Strong Fit (Waist): Relaxed Length: Slightly long I wore size S. The hips and thighs have a solid amount of military-style volume. The waist can be adjusted with the adjusters or a belt, so even with my slim build, I was able to wear them without any issue. |
| ●Staff Height / Weight: 171cm / 70kg Worn Size: S / M Body Type: Standard Thigh Area: Standard / Strong Fit (Waist): Just right / Relaxed Length: Just right / Slightly long I wore sizes S and M. If you want a cleaner fit, size S is recommended. If you want to enjoy the original wide oversized silhouette of the M-51, size M looks great. |
| ●Staff Height / Weight: 177cm / 73kg Worn Size: M / L Body Type: Standard Thigh Area: Standard / Strong Fit (Waist): Just right / Relaxed Length: Just right / Slightly long I usually choose size L, but this pair is made larger, so size M gave me just the right wide fit. The waist also felt just right with no tightness. If you want to emphasize a looser, more rugged look, choosing size L and trying a suspended style using the suspender buttons would also be a good option. |
| ●Staff Height / Weight: 181cm / 78kg Worn Size: L / XL Body Type: Sturdy Thigh Area: Strong Fit (Waist): Just right / Relaxed Length: Just right / Slightly long Size L gave me a very satisfying loose fit with just the right amount of room. Even with my sturdy build, I felt no tightness at all around the thighs or hips. If you want to add even more volume, size XL also seems like a good choice. |
