Eric of Revelate makes the Bar Mitts? Didn't know that.
I've checked out most of the commonly known "Pogies" but I have never owned a set. I bought a Pugsley last October and rode it til I finished my Moonlander a few weeks ago but due to the mild winter many of us experienced, I just used some gauntlet ski gloves. Not entirely sure where my preferences stand, although I will add that I wasn't entirely sold on neoprene. That said I don't have much to base that off of.
I also looked at getting a set of Kevin Kinney of Empire Wool and Canvas' "Ice Bike Mitts" but I think I'd like to wear thinner gloves and have the weather protection for the brakes/grips would be a plus. It may very well be that I try a few different things until I find what suits me better!
