SPECIFICATION PROTOCOL 
System Overview
An unlined, midweight outer layer engineered from calibrated 100% cotton denim, structurally optimized to transition seamlessly between controlled microclimates and changing urban environments. Developed with an open architectural silhouette, this overshirt minimizes body-to-fabric contact to ensure natural kinetic thermal regulation while functioning as an independent protective module or a technical mid-layer infrastructure.
Architectural Ergonomics (Design)

High-Volume Zero-Friction Silhouette: Cut with a disciplined, low-drag oversized volume that forms a physical protective drape over internal base layers, completely eliminating underarm and shoulder resistance during active physical locomotion.
Modular Multi-Vector Utility: Features a straight hem geometry with dual-purpose mechanics; can be deployed fully closed as a thermal boundary layer or unbuttoned as an ultra-light tactical jacket matrix.
Industrial Structural Closures: Engineered with three heavy-gauge, high-density alloy buttons finished in an anti-corrosive gold-tone polymer coating. The hardware acts as secure structural anchor points against high wind vectors while maintaining visual contrast within a clean, monochromatic environment.

Textile Engineering & Fabric Core

Calibrated Midweight Denim Shell: Constructed from high-density, ring-spun 100% cotton weave. The structural layout provides maximum resistance to abrasion and environmental wear while retaining a soft, broken-in tactile response against the epidermis from initial wear.
Tensile Yarn Stability: The cross-sectional warp-and-weft distribution delivers balanced flexibility and high physical resilience, ensuring the oversized shape does not distort under mechanical load or standard laundering exposure.
