What temperature range are you looking for? For summer riding the BioRacer AeroMesh https://www.bioracer.be/en/team-clothing/41446/jersey-ss-race-proven-aero-mesh jersey is absolutely the best jersey I’ve ever worn. It was so good that I went on Alibaba and have my own version made (which was maybe 90% as good.) the BioRacer SpeedConcept jersey is also very nice but can’t wear that on hot days. I also have a NoPinz Trip jersey (made to measure) but the BioRace jersey fits me better so it probably wins the aero competition. I also had a Rule 28 jersey. It doesn’t use any fancy “aerostripe†materials but it was very nice and fit like a glove.
Things I suggest looking for: the best fit with minimal wrinkles in your riding position, sleeves to the top of the elbows as skin is slow, I hate collars but don’t know it’s that make it any more aero or not and finally buzzwords like Monica, Speedsilk, aerostripe, etc. when looking at the fabrics.
I like the mesh construction of the Bioracer jersey. I suppose you design your own? Any minimum quantity and what are the prices?
Borah has a similar selection of jerseys with a minimum of 5 per order as they are geared toward teams.
