Are all non-stretch shell jackets always going to be "poofy" to some extent? I'm a little on the fence on keeping a jacket I just bought.

I have a hardshell jacket from castelli, and the chest always has a little bit of "poof room" it seems when I am in the drops for example. The softshell seems to stretch with me, just like a jersey would. I'm pretty sure the size is correct, it seems to be a matter of cut/fabric.

Most shell-type jackets I've tried on in varying cuts seem to be similar in this way too.

Whats your experience?
