Fynn - It's a great point. The gilet has never made sense to me since I have no problem keeping my core warm.

gbg - my way of saying I need to keep warm, but I'm not worrying about waterproof, because screw biking on wet roads. It might make me a wuss, but I hate wet feet, and I really hate how much grit accumulates in the chain and on the bike... it's like 6 months of dry riding = 1 day of rain riding in terms dirt accumulation.
