I've got loads of high quality wool and synthetic gear from the top names. But, to be honest, I've never really tested them yet in really bad conditions. I'll usually go out for a full day of hunting or hiking, but i'm never out there overnight or for several days. I've read the usual stuff about wool being warm while wet, or the new synthetic puffies being warm while wet, and I've read about Buffalo/Pile/PCU type synthetic stuff that can be walked dry. Just wondering if any of you can give HONEST feedback about being soaked for a good part of the day on a cold day while wearing wool and synthetics and if you can tell us what your experiences were like. Did the clothing and materials work as they are often advertised or touted to be? Do you think it might have actually saved you from being hypothermic? Do you think a lot of it is overhyped? Would you change anything about your layering system? Thanks for any feedback.
