Materials & Construction
WTV 300 Wind Thermal Ventilation Fabric
The Chilco Snap Shirt is constructed using 7mesh’s WTV 300 fabric, a performance knit engineered to balance wind resistance, breathability and thermal comfort. The outer surface features a smooth, structured knit that reduces light wind penetration while maintaining a refined, shirt-like appearance suitable for everyday wear.
The fabric blend of 57% polyester, 34% recycled polyester and 9% elastane provides durability with built-in stretch. The elastane content ensures natural mobility through the shoulders and arms, allowing unrestricted movement whether you’re reaching, hiking or layering. The recycled polyester content reduces environmental impact while maintaining structural integrity and long-term performance.
High-Loft Thermal Backing
Inside, the fabric features a high-loft brushed backer that traps warm air close to the body. This lofted construction enhances thermal efficiency while remaining breathable enough for moderate activity.
The brushed interior feels soft against the skin and adds comfort during extended wear. It provides insulation without bulk, allowing the shirt to function as a light outer layer or midlayer depending on conditions.
Structured Yet Flexible Construction
The knit structure offers light wind resistance without the stiffness of a membrane-backed softshell. This gives the Chilco Snap Shirt a natural drape and relaxed silhouette while still providing meaningful protection in cool, breezy environments.
Slits at the side hem enhance freedom of movement and improve comfort when seated or layered. The fleece-lined inner collar adds additional warmth and reduces irritation around the neckline.
Sustainable Fabric Certifications
The Chilco Snap Shirt is built with responsible material choices that reduce environmental impact without compromising performance or durability.
Recycled Content
The main fabric incorporates recycled polyester, reducing reliance on virgin raw materials while maintaining strength, stretch and long-term resilience. Using recycled fibres helps lower overall energy consumption and resource demand during production.
bluesign® Approved Fabric
bluesign® approval ensures the fabric has been manufactured under strict chemical management standards. Harmful substances are removed from the beginning of the production process, protecting both the environment and the people involved in manufacturing.
OEKO-TEX® Standard 100 Certified
OEKO-TEX® certification verifies that every component of the fabric has been tested for harmful substances and is safe for direct skin contact, especially important in garments designed for all-day wear.
PFC & PFAS-Free Construction
The Chilco Snap Shirt is made without PFCs or PFAS, fluorinated chemicals often used in textile treatments. Eliminating these persistent substances reduces long-term environmental impact while maintaining dependable everyday performance.
Features
Low-Profile Snap Closure
A clean front snap closure provides quick fastening while maintaining a classic shirt aesthetic.
Chest Pockets with Snap Closure
Two clean chest pockets with secure snap closures keep small essentials safe while preserving the shirt’s streamlined look.
Fleece-Lined Collar
A soft fleece interior at the collar enhances warmth and next-to-skin comfort, particularly in cooler conditions.
Side Hem Slits
Slits at the side hem improve mobility and allow the shirt to sit naturally whether layered or worn untucked.
Dual Hanger Loops
Two integrated hanger loops add functional convenience and pay homage to classic shirt detailing.
