Kind of redundant to have both to be honest. There is enough integrity to the TU muffs that they won't blow against the levers like other muffs I think. Either way it wouldn't have solved my problem with width.

I would say that down below 0'C for long periods and with precipitation then the gaucho would help a lot. In the rain I found that the toes of my boots showed rain on the outside, but from the toes up to my helmet was nothing.
