These are a fantastic well thought out pair of ultra warm down trousers! As I’m in the uk i thought it was only fair to try them out on our highest mountain Ben Nevis. I had no problem putting them on with the zips at the sides so no messing about taking boots off. Very comfy and no restrictions in movement. Packs very small into its own bag and very lightweight. I’m heading back to Nepal next year and these will definitely be coming with me.
