Given that the British weather is reverting to type I'm looking for a waterproof short sleeve jersey for the changeable rainy/sunny days. I've always fancied the Castelli Gabba but have also considered the Café Du Cycliste Josette Jersey. I'm aware the the gabba is the choice of the pro peleton but in terms of styling I lean more towards the minimal aesthetic of rapha than logo-heavy pro kit, so the Josette is catching my eye more than the gabba. That said, functionality and performance are my highest priorities.
Both are pretty much the same price so I'm just wondering if anyone has experience of either jersey? Or both?
My concerns are:
How long does the waterproof treatment last?
Do I need to wash it with tech-wash? If so, every time? Every other time? Once in a blue moon...?
If I wore it on a day like today (20C with some pretty heavy showers) would I overheat in between showers without having the zip fully open?
