uhhhhh lemme correct you on a few things here.I'll bite. The guys who recommend Puffy/Hard shells for the most part are rifle hunters. Their pack contains one underwear bottom and one Merino top they wear all week long to go along with their puffy and hardshell.
No self respecting archery hunter would dare to go with the above mentioned setup. That's why they make quiet mid layers like the Sitka Traverse zip T or Kuiu Peleton and Softshells like the Sitka Jetstream.
Hardshells to me are rain gear . Puffies are too fragile as an outer layer.
I worry more about getting in shape than crying about the slight additional weight of a softshell but that just me.
usually the guys that recommend the puffy and hard shells are the ones that are hunting in the mountains.... not in a deer stand in idaho... no self respecting archery hunter going after sheep/ mountain goats would be caught dead holding up some rock chutes with a softshell on.... soft shells have their place but for any serious backpack mountain hunts they don't hold their value in weight... ive taken everything from white tail, elk, mountain goats and have never once though geee my puffy and hard shell is really holding me back
