Materials and Construction
Main Body: 70D Recycled Nylon Blend
The primary fabric uses Bluesign-approved 70D nylon (85% recycled) blended with 15% spandex. This combination provides lightweight durability with stretch, allowing the vest to move naturally with your stride while maintaining structure and load stability.
Contact Mesh: Recycled Polyester Airmesh
Body-contact areas feature Bluesign-approved, 100% recycled 75D polyester airmesh. This breathable mesh improves airflow, enhances comfort against the skin and helps manage heat during high-output activity.
All fabrics meet bluesign standards, ensuring responsible chemical management, reduced environmental impact and high manufacturing quality.
