A caveat: I bought this:
 
	
		
			
		
		
	
		
		
	
	
		 
	
	
		
			
		
		
	
 
For a week's commute it was fine, better than fine actually, the fact that nylon threads were 'leaking' from the zip, was not a problem (even when I found some of them in my cassette) On a very cold day I cycled to work and afterwards to the pub and was as warm as toast, on the way home from the pub I had to take off a layer (it was VERY cold) The 100% clincher was that there is stitching directly across my shoulder blades, and after a week I cannot bear to put it on. If I were to write that it was 'painful' I am sure that I would be encouraged to MTFU, but I will say that it is EXCRUCIATINGLY annoying, such that I cannot bear to put the damned thing on ever again.
