This past winter I ordered a set of Moose Mitts and due to production delays they still haven’t arrived. Moose Mitts, like Bar Mitts, go over your bicycle handlebars and allow you to place your gloved hands inside to keep them warm.
Update: I received my Moose Mitts once production restarted in November 2011. This is an excellent product that is available for MTB and road bikes. See my Moose Mitts product review that was published on December 9, 2011.
