This thread has appeared regularly on 24hr for going on 20 years. I dunno the right answer, but the consensus has always been that the Mtn Hardware Ultra Lamina and Lamina were good buys, the Lithium was good, and everything WM was great, and Wiggys and Big Agnes used to be. Nobody can answer the down/synthetic question but the user. What works on Mt. Everest is immaterial for most hunting and backpacking. We get wet from the outside and bad. For myself, I have concluded that high-quality down is worth the price dif from average down.
