I have some of their t-shirts with weight and volume less than half than of typical cotton ones, and a 'spark' insulated top which weighs very little but is very snug and water-resistant (and reversible between yellow or dark blue).
Aldi did some synthetic short sleeve shirts a while ago. About £7.
Really good. Various colours of a sort of checkie pattern.
Dry in no time.
Worth keeping an eye out - they were in one of its specials, though not a cycling one as such.
