Thanks for the info, everyone! For the price, it looks like the DriDucks are the ticket for my purposes. Before I buy though, I'm going to look a bit more for an equally light suit that could double as a vapor barrier liner in my sleeping bag. So far, the only thing I've seen are vinyl suits for weight loss in Walmart. However, they felt to weigh a pound or more. If anyone knows of a similarly cheap suit, that could be used a VBL and is as light as the DriDucks, please post.

Thanks!
