I've been rolling the same ever since they first came out a few years back...they do make a difference for me. Full-length zippers make on/off easy and fast without removing your boots. They stuff very compactly and zip-close easily into their own pocket, and at .6 they are worth their wt for me.Not synthetic but I've been using Kuiu Super Down Ultra @ 8oz for the last two seasons. Got by without for decades but they do make a nice difference in comfort.
looking for opinions on puffy pants for last ten days of August,leaning towards synthetic maybe nanutuk 2.5 instead of the 3.5’s. Times getting short so need to get a order in soon,Thanks for any opinions Billy
