I was thinking gabba in yellow, long sleeve.............right-dont go for a softshell. It will be far too hot for you. I use a fairly cheap Planet X Biemme top. Slightly fleecy but thin. Worn all last winter with either one or 2 combo of baselayers. Or an old Altura autumn jacket and, as above,with layer combos.
If I was buying something now I would go for something like a Sugoi, Castelli etc.
