Lightweight, durable, and breathable Designed by our team of all-mountain and enduro riders, this MTB jersey combines lightness and durability. Its mesh fabric ensures optimal breathability. Its loose fit with raglan sleeves guarantees complete freedom of movement and effective heat and moisture wicking. "R TONE" is a double reference: to the Brazilian Formula 1 driver Ayrton Senna and his country, Brazil, through the colors.
