Thanks for the reply. Would you say wearing this in negative teens to 40 would still have you sweating with being able to breathe? I have an old Cabelas MT050 Extreme from 20yrs ago im wanting to replace. I've got a late season here im trying to figure out a setup for. From another post I've now eliminated the Kutana Gale Force as the inseam is 34" and I cannot make that work for pants as my legs are too shortI'd hate to steer you wrong, by making a size recommendation. The model I tested is a generation or two back, I'm not familiar with the newer model. I still think calling Sitka is your best bet. Sorry I can't be more helpful.
