In reply to GrahamD:
I reckon a fair number of us actually use Scottish English, Welsh English and Irish English
Looking forward to a pair of backcountry kegs, or breeks.
(I do actually agree with you about "pants" but hey, I've been stuck in a van in continual rain for the last 7 days, and I just ran out of gas, so I'll join the UKC troll catharsis™!)
In reply to captain paranoia:
From my limited time in the Simonds, I would put them as around as warm as the Gucci's. Which for me is perfect for touring in the actual cold months, although I run cold and will often have the thigh zips down - a big component of what makes these trews so good, and I still reckon having "fart chimneys" that didn't chafe would be possible and increase ventilation even further.
In spring I do often end up rolling them up into shorts for the ascent! One day when I'm rich enough to afford more than two pairs of trousers (or when my terras finally die and I look for a summer replacement) I would be keen to find something lightweight with removable mini-gaiters.
To the OP best way as always is to try on a bunch of different things and see what suits. Unfortunately decathlon are usually pretty bad at stocking Simond in store, but you can always order online and return what you don't want.
