Details details. Hoy Vulpine wanted to take an all time cycling classic and move it on with the Hoy Vulpine Women’s Valldemossa Race Jersey. So they haven’t messed with the basics, but nailed the details. First they chose a softer, more comfortable and flattering fabric, with S.Cafe technology to defeat odours and make a faster drying jersey. It’s even more UV resistant, for days in the heat.
