Respirtech jacket

I recently got a new jacket. I'd always used a black one but thought I'd try something different and got a colored one. I feel it's not doing as good a job as the black one; it's not as tight and I don't feel like it gets the upper lobes as much. To those using the Incourage, do you use a colored vest and find it's doing its job? Thanks!
