As biped says, slim fit, have a pair of trousers for general climbing, fantastic cut, very hard wearing, to the chagrin of my other half, i live in them.
Must say very impressed with Sherpa gear and it's ethos.
The trousers i have, stretch and are incredibly light, you barely notice them, cragging , bouldering, walking they really are the best i have used, had for over a year now and still going strong, i would buy another pair.
I have a pair of sherpa winter softshell trousers , fleece lined, super warm, well made , the fit is good although they are slightly long. I have a regular length in most makes but the sherpa are slightly longer, I'm 5, 7 so fairly short though
I have quite a few items of Sherpa clothing and would agree the fit of both jackets and trousers is pretty slim. I know some of the women's hard shells have very narrow fitting arms. I've got a very stretchy softshell jacket and some stretchy lightweight climbing trousers, both have worn very well.
