Buzz Rickson Men's Denim M-51 Field Trousers - Military-Inspired Baggy Cargo Pants in Indigo Denim - Made in Japan (BR42586 421A One Wash)

Buzz Rickson

These men's casual baggy denim cargo pants are made in Japan by Buzz Rickson, a militarywear-focused brand under Toyo Enterprises renowned for its vintage-inspired craftsmanship. As part of Buzz Rickson's U.S. Army collection, this model is a modern reinterpretation of the U.S. Army M-51 Field Trousers, reconstructed in rugged indigo denim. Expertly crafted with the brand's signature attention to detail, these pants capture the authentic features and character of classic American military garments while balancing heritage aesthetics with modern wearability, blending seamlessly into today's casual style. The fabric of these pants is a 100% cotton, non-stretch, heavyweight indigo denim. Woven with indigo-dyed warp yarns and undyed weft yarns at a high density, the fabric has a rugged, textured surface with a firm, structured feel and exceptional durability. As part of the finishing process, the garment is pre-washed (also known as one-wash) to minimize shrinkage and achieve a vintage-inspired appearance. These pants faithfully reproduce the design of the original cold-weather overpants. The design includes two front hand pockets with flap covers and concealed snap buttons, two rear flap pockets with hidden snap closures, and two large pleated cargo pockets with concealed snaps on both thighs. The exterior waistband is equipped with urea buttons - two on each front side and two at the back - for attaching suspenders, while adjustable side buckle tabs allow for a customized fit at the waist, along with six belt loops. Additional utility details include cord loops positioned at the upper front and inner back waistband to accommodate hook-type suspenders, and interior button tabs for affixing an optional removable liner (liner not included). The knees are pleated to enhance mobility. Each leg cargo pocket conceals a set of cotton leg ties. These ties can be pulled out through a buttonhole-style slit located on the inseam side of the leg cargo pocket and threaded through two small loops positioned at the crotch area, allowing the wearer to tie them around the thighs. This feature was originally designed to keep the cargo pocket's contents from shifting during movement and to prevent the pants from sagging when carrying heavier items such as ammunition or rations, enabling the wearer to secure the pant legs as needed. Internal drawstrings at the hem provide further adjustment to seal out wind and debris. Please note that these trousers are sold as a standalone item and do not include a cold-weather liner or suspenders. These pants feature a baggy straight fit with a high-rise waist, zip fly, and full-length leg. They have a distinctly loose, overpant-style silhouette with an extra-wide leg, faithfully replicating the original design's purpose as a shell layer. The cut is generously relaxed through the seat and thighs, falling straight to the hem for a roomy, comfortable fit reminiscent of vintage military field trousers. This new original release from Buzz Rickson expertly combines vintage military aesthetics with the brand's renowned attention to historical detail, reimagined in rugged indigo denim.

Model: A modern reinterpretation of the U.S. Army M-51 Field Trousers, originally issued in 1951, now reconstructed in durable indigo denim.

Fabric: These pants are made from 100% cotton, non-stretch, heavyweight indigo denim. The fabric is densely woven using indigo-dyed warp yarns and undyed weft yarns, giving it a rugged, textured surface with a firm, structured feel and outstanding durability. As part of the finishing process, the garment undergoes a pre-wash treatment (also known as one-wash) to reduce shrinkage and produce a vintage-inspired appearance.
