I believe I purchased these around 2019, but I'm not certain. I only wore them outside once to try them on, and they've been stored at home since then. I worked hard to buy them at the time, but they're over-spec for me now, so I'm putting them up for sale. Please note that there is no box. There is no hydrolysis. I'm decluttering my mountaineering gear. If you're considering your first pair for the severe winter season, how about these at a low price?
