Maintenance
The OS2O Summit Skimo Suit is made with high-performance technical fabrics, 80% of which are sublimated. To preserve color quality, elasticity, and technical properties, follow these recommendations:
Machine wash cold (max. 30°C) on a delicate cycle.
Use mild detergent and avoid fabric softeners or bleach, as they may 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 aggressive chemical products.
Following these guidelines will ensure maximum durability and performance of the garment.
