WILDSIDE×SPIEWAK G-8 FLIGHT JACKET

Based on SPIEWAK’s iconic “G-8” flight jacket, originally adopted by the U.S. Navy Air Corps in the 1950s, this piece has been reinterpreted through the WILDSIDE lens with refined detailing and modern updates.
Crafted from Yohji Yamamoto’s original premium wool gabardine for the outer shell and lightly padded for insulation, it offers both warmth and functionality as a fall/winter outerwear essential.
While preserving traditional elements of the original “G-8”—such as oversized flap pockets on the chest, a cigar pocket on the left arm, a chin strap with ribbed fabric, and action pleats at the back—this updated version introduces a double-zip front closure and additional side pockets, blending contemporary style with practical utility.
A one-of-a-kind piece that fuses military heritage with modern mode sensibilities, true to the spirit of WILDSIDE.

『SPIEWAK』
Founded in New York in 1904 by Isaac Spiewak, this storied American military brand has stood for over 120 years.

Isaac, an immigrant, first crafted sheepskin vests, which quickly gained popularity among dockworkers. During both World War I and World War II, the brand supplied jackets and trousers to the U.S. military, earning a reputation for exceptional reliability.
Even today, its rugged Titan Cloth jackets are officially adopted by police, fire departments, and other public institutions, while also serving as workwear for polar expeditions—proof of the brand’s enduring trust in durability. Celebrated worldwide, its unmatched functionality and timeless style continue to be highly regarded across generations.
