A question on your feet - would you say your system keep your feet dry, wet but warm, or wet and chilly. If you were planning a much longer trip, say a one to two week trip in conditions around freezing, would you change anything with your footwear system?
Edited for second question after watching your video.
The neck gasket looks very loose on you. Is that how it came, or did you stretch/trim it to make it more comfortable?
