Hello,
I want to get an ultralight camp jacket for this winter, either an Ex Light Down Anorak or maybe the Plasma 1000. I have not tried on any Montbell gear so I do not have an in-brand reference and there is no place around me to try something on.
I am 6’1″ 185lbs. With empty lungs I measure 39″ circumference under my armpits and 41″ with full lungs.
This puts me solidly in the Medium size, but I have an athletic build and often find medium’s tight in the shoulders when my arms are outstretched (like when cooking or doing anything on the ground)
I am a Large in Arcteryx base layers and trim cut items, but their baggier cut items I can fit a medium comfortably.
So, what say you BPL? Should I go with the size chart and get a Medium or do I go up to a large?
If you can comment on your height/weight/chest circumference with an empty or full breath, this would be most helpful.
Thanks!
