I have alot of Assos stuff and it is without a doubt the best quality stuff out there. Their AirJack 851 and 3 glove system is awesome. The jacket I have worn under a jersey in 30 degree weather and felt OK throughout a 35 mile ride. I have never seen such impeccable quality in clothing anywhere.

My girlfriend once asked me if they made handbags after reviewing the jacket.
Descent and Capo higher end stuff is not far away from assos along with some others.
Sugino is cheap junk and so is ascent.
