I’ve got a few weights of trousers I can use for standing still/ being in the cold, depending on how still I’m standing, and how cold it is.
layering for the win – All your trousers can now be warm trousers. Even those crappy old crotchless jeans will still be good for allotment/gardening jobs – keeping the mud and scuffs at bay over the warm layer.
Unders:
– 2 x merino longjohns,
– some microfleece polartech 3/4s I’ve had for snowboarding – I’m wearing those now under some – climbing-type, slightly stretchy cotton trousers,
– some powerstretch long johns – those are for standing really quite still in, when it’s pretty cold. would be good for touchline duties.
Overs:
– windproof synth puffy overtrousers for a winter camping expedition. full-length zips for quick deployment over what you’re wearing without taking your boots (inc your big one, OP!) off. Marvellous. Desperate measures for SE UK, though. broken heating, winter camping evening wear sort of thing.
– RAF surplus goretex overs to keep the wind off – just as handy as the unders for staying warm.
