I have a metro but I never bothered buying the winter kit; I already had a J&G rain cover and that's all I've ever needed in the winter. The year before that I just taped up the vents, and I'd still do that before buying the winter kit. I mainly bought the metro because it was on clearance for $35 and it's a nice helmet, and it fits my head (one of the few that does).
