Seriously? I thought there was supposed to be some kind of mystic stuff going on with gabba and it losing its water repellantness if you washed with regular detergent. So yours still beads water properly?
Dunno. I don't really care about water beading, I like it cos it's still warm when it's wet and it's cut well. I couldn't imagine not washing a jersey after a 3 hour ride, I'm not a barbarian.
Mine gets washed after every ride the same as the rest of my riding kit, as far as I can tell it still works.
