I see that Montane is a British company, so sizing may be different, and I've read some size comments. But I'm still trying to triangulate the best size for me. I wonder if anyone out there reading may be about my size, has worn the NS and can give a definitive suggestion? I'm 6'4", 185-190, on the slender-athletic side of things. Every athletic jacket I own is from a US company and large is always spot on, but perhaps this rule may not hold here. I prefer athletic clothing to be more fitted than billowy, but still want to be able to move well. Thanks for any suggestions.
