Built for movement and transformation, modular outerwear represents Napapijri’s commitment to purposeful design. These adaptable jackets combine form, function and craftsmanship, responding to the ever-changing demands of modern life and weather with intelligent construction and clean, versatile style. 
What is modular outerwear?
Modular outerwear refers to jackets and coats designed to adapt to different environments and conditions. The concept brings versatility to the forefront of design, featuring detachable or interchangeable elements such as sleeves, insulated liners, hoods and hems.
Rooted in the modular fashion trend, this approach supports a more intentional wardrobe, garments designed to serve across settings and seasons. Whether water-resistant or reinforced with advanced weatherproofing technology, each modular jacket reflects Napapijri’s philosophy of functional innovation and contemporary design.
The Biez Modular Puffer Jacket embodies this idea, designed with detachable long sleeves and a stow-away hood. It transitions seamlessly from full-sleeve outerwear to a sleeveless gilet, offering flexibility without compromising performance or aesthetic.
How do 2-in-1 jackets work?
A 2-in-1 jacket system brings together an outer shell and an inner layer that can be worn together or separately. This modular construction allows the wearer to adapt insulation and protection as conditions change.
The outer shell provides a lightweight, water-resistant barrier, while the inner layer delivers warmth and comfort. When combined, they create a cohesive system that performs effortlessly in unpredictable weather.
Detachable elements such as hoods or sleeves extend this flexibility. Hoods can be removed or stowed away to achieve a cleaner silhouette, while adjustable hems and cuffs help refine fit and functionality. Every component is crafted to integrate seamlessly, from reinforced zips to ripstop fabric and taped seams that enhance durability and structure.
Benefits of modular design
Modular design follows a function-first philosophy, balancing adaptability with refined simplicity.
Versatility
One piece, multiple forms. Modular outerwear transitions easily between environments and occasions, blending technical performance with urban practicality.
Adaptability
Built to respond to shifting temperatures and weather conditions, modular jackets allow layers and components to be added or removed as needed.
Smart design
Each detail serves a purpose, lightweight materials enhance movement, while robust fastenings ensure durability. Modular pieces are engineered for longevity and ease, combining precision with understated style.
Effortless styling
A modular jacket integrates smoothly into both outdoor and everyday wardrobes. It offers freedom to reinterpret a single silhouette in multiple ways — a quiet reflection of modern, adaptable living.
Are modular jackets sustainable?
Modularity promotes conscious consumption through design longevity. By fulfilling the role of multiple garments, a modular jacket reduces the need for frequent purchases while extending product lifespan.
Napapijri’s modular approach encourages buying less and wearing better. High-quality materials and thoughtful construction support durability, ensuring each piece endures over time. Sustainability here is not a separate feature but an inherent result of design built to last.
We believe that sustainability is the new creativity, inspiring new ideas, paths, and innovation. This design philosophy guides our effort to reach 100% of materials from regenerative and responsibly sourced, renewable or recycled sources by 2030 through four strategic pillars: circularity, durability, traceability, and better-sourced materials.
