Materials & Construction
WTV 300 Wind Thermal Ventilation Fabric
The Chilco Vest is constructed using 7mesh’s WTV 300 fabric, engineered to balance wind resistance, breathability and thermal comfort. The outer surface features a tightly knit structure that reduces wind penetration while maintaining flexibility and durability, making it suitable for repeated outdoor use.
The fabric blend of 57% polyester, 34% recycled polyester and 9% elastane provides durability with natural stretch. The elastane ensures unrestricted movement through the torso and shoulders, allowing the vest to move naturally with your body, whether you’re climbing, riding or layering. The inclusion of recycled polyester reduces environmental impact while maintaining long-term structural integrity.
High-Loft Thermal Backing
The interior features a high-loft brushed backer that traps warm air close to the body, providing efficient core insulation without excessive weight. This lofted construction enhances warmth while remaining breathable enough for moderate activity.
The brushed inner surface improves next-to-skin comfort and prevents clamminess, helping regulate temperature during fluctuating effort levels in cool conditions.
Structured Yet Flexible Design
Unlike membrane-backed softshells, WTV 300 offers light wind protection without stiffness. This gives the Chilco Vest a natural drape and relaxed silhouette while still delivering meaningful protection in breezy conditions.
The contrast pocket fabric, composed of 80% polyester and 20% elastane, enhances durability and stretch in high-use areas while maintaining overall comfort.
Sustainable Fabric Certifications
The Chilco Vest is built with responsible material choices that balance environmental awareness with long-term durability and performance.
Recycled Content
The main fabric incorporates recycled polyester, reducing reliance on virgin petroleum-based fibres while maintaining strength, stretch and thermal efficiency. By using recycled materials, overall energy consumption and raw resource demand are lowered without compromising structural integrity or everyday resilience.
bluesign® Approved Fabric
bluesign® approval ensures the fabric has been manufactured under strict environmental and chemical management standards. Harmful substances are removed at the source, and resource use — including water and energy — is carefully controlled throughout the supply chain.
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. This is especially important for garments designed for active layering and extended wear.
PFC & PFAS-Free Construction
The Chilco Vest is constructed without PFCs or PFAS — fluorinated chemicals often used in textile treatments that persist in the environment. Eliminating these substances reduces long-term ecological impact while maintaining dependable wind resistance, warmth and cold-weather performance.
Features
StashSystem Packability
The vest packs neatly into a zippered StashSystem pocket located at the lower back, making it easy to store when temperatures rise.
Integrated StashSystem straps let you attach the packed vest directly to your bike for convenient access in changing conditions.
Soft-Touch Neck
A soft-touch interior at the collar enhances comfort and reduces the risk of chafing during extended wear.
Core-Focused Thermal Protection
Sleeveless construction delivers targeted warmth to the torso while allowing unrestricted arm movement for active pursuits.
Fit & Feel
