Nev, I know you and Jo trek around all over the place and in all weather. Re your endorsement of the Buff's warming qualities - you know how cold it gets in Canberra, right? You reckon a Buff would be enough here in the depths of winter??? I have always used a neck-sock, despite finding it a bit bulky (better than freezing to death tho!). Tried a silky-type balaclava but found it obscured my peripheral vision and was so annoyed by it that it didn't last the distance to the next petrol stop, let alone the next bit of cold weather!. Is the Buff substantially better than other options? I'm not unhappy with my neck-sock, but it IS a little bulky... betty
