I tried some of the bib tights and they are a no no for me, terrible fit, padding etc - although I do know a few people who have used the jackets sussessfully.
Each to their own I suppose, I still find the buy cheap buy twice very apparent when it comes to cycle clothes, especially winter ones. Personally I want confidence that my kit will keep me warm and dry throughout those long winter rides and £10 kit from a supermarket isnt convincing.
