I wear a Buffalo mountain shirt and do not 'run hot'.
I use it for most Scottish weather except the warmest, or the very coldest (-I use a tecmax Buffalo at serious minus temps.) It is my 'go to' top layer for general walking. It can be too warm on ascents, but deals with wind and damp superbly, especially on the tops. I wear a lightweight merino base layer underneath -as taking it off and going 'bare topped' isn't usual dress code for female walkers. Buffalo shirts do nothing to enhance your 'female curves' but it is the ultimate in utilitarian usefulness. I find the pockets are the best placed of any jacket I have used.
I first bought one on impulse and it is now my most used piece of outdoors clothing.
