I looked at a bunch of those brands and ended up buying a jersey from Stolen Goat. I love it. I also got a Roka warm weather jersey which is awesome, but the sizing is whack. I’m 5’ 10" and 170# and wear a medium in pretty much everything, but the Roka medium wouldn’t have fit if I were 150#. I exchanged it for a large and it’s all good.
I just bought a sweet new jersey in Spain, made there by a company called Gobik. Very light and airy. Check them out – http://store.gobik.com/coleccion.html
Edited to add, I’m a female about 5’3", and got the “Maillot CX Pro Unisex Orange Desert” in a size S. It fits plenty snug… race fit.
i actually rode with the founder today (had no idea till halfway into the ride), strong rider, nice guy.
a bunch of my friends wear velocio and really comment on the quality of it. the only reason i don’t have any is because i have sooooo many jerseys and bibs. but i’m 100% buying velocio for my next bib/kit
