Technology
COOL2DRY®
Cool2Dry® is a lightweight, stretchy technical fabric (120 g/m², 90% polyester – 10% elastane) designed for comfort, freedom of movement, and high performance during intense activity
The back and underarm areas incorporate a 100% polyester mesh (100 g/m²), strategically placed to enhance breathability, increase abrasion resistance, and improve comfort when wearing a hydration vest
Both fabrics are made in Spain, ensuring quality, proximity, and commitment to local production
Maintenance
The OS2O Trail T-Shirt is made with sublimated high-performance technical fabrics. To preserve color quality, elasticity, and technical properties, follow these guidelines
Machine wash cold (max. 30°C) using a delicate cycle
Use neutral detergent and avoid fabric softeners or bleach, as they can affect breathability and sublimated colors
Do not tumble dry. Air dry flat to prevent deformation
Do not iron. Direct heat may damage the fabric structure and sublimation
Do not dry clean or use harsh chemicals
Following these instructions will ensure maximum durability and performance of the garment
