Honestly, I could buy nice wearing and fitting stuff from Giro, Giordana, Assos, etc., but Velocio is doing something extra, something special that I'd like to see become the 'norm'. Using recycled fabrics! That being said, the fit of Velocio's jersey, bibs and just about everything I've bought is perfect. I'm 6-ft 1.5 inches tall, and 170-175 lbs., and the wear a medium in the Signature jersey. A really versatile jersey, as I've worn on warm-to-hot days, and colder days with arm warmers and wind vest. I'd call it a 3-season jersey. Lastly, SS arm length is perfect. I like it a little long in the short sleeve arms to help with sun/wind protection. Keep making great stuff, and I'll keep buying it, and by the way, thanks for giving a sh*t Velocio, happy to see more companies step up and do the right thing.
