Fit Notes: This vest runs slightly small compared to standard American sizing. If you usually wear a size M in American jackets, we recommend selecting a size 42 (L) in this vest.

The Flat Head 12.5oz Denim Puff Vest
The Flat Head 12.5oz Denim Puff Vest is a masterful blend of traditional Japanese denim craftsmanship and functional cold-weather design. Built around a naturally indigo-dyed denim shell, this vest showcases the unmistakable depth and vibrancy of true Aizome (natural indigo)—a color that develops rich character and nuance with wear over time. The denim itself is woven on vintage shuttle looms, giving it a subtly uneven texture and a soft, organic hand that elevates the vest beyond standard outerwear.
The upper yoke is constructed from Ultrasuede® Nu, a premium synthetic suede known for its leather-like appearance, durability, and ease of care. It offers a smooth, refined contrast to the denim while remaining lightweight, flexible, and resistant to color transfer. Unlike real leather, Ultrasuede® can be safely dry-cleaned and spot-cleaned, making it ideal for everyday wear without compromising aesthetics.
Insulated with high-performance padding, this puff vest delivers excellent warmth without excessive bulk, making it a versatile layering piece across seasons. Whether worn over a flannel, sweatshirt, or light jacket, it provides reliable insulation while maintaining freedom of movement.
Functionality is thoughtfully executed throughout. The vest features two large hand-warmer pockets at the waist—deep enough to securely hold modern smartphones—as well as two interior pockets for additional storage. A selvedge denim hanger loop at the collar subtly highlights the garment’s shuttle-loom heritage, while custom bronze snap buttonsengraved with The Flat Head branding complete the piece with a classic, understated finish.
Built with longevity in mind, this vest reflects The Flat Head’s uncompromising approach to materials, construction, and authenticity—an exceptional outer layer that balances heritage, performance, and timeless style.
