I, for instance, thoroughly enjoy going back to my woodland home and putting on my warchief bulwark before heading out to do something important. http://tinypic.com/view.php?pic=312zlzc&s=8
If I am just goofing off, wandering around in a warmer part of Skyrim, ( I use Frostfall/Hypothermia) I will usually just wear whatever, but the bulwark comes off the mannequin whenever some serious ish is going down. It's been through several good battles with me and has never let me down.
Do you have a favorite armor, vanilla or modded in, that you prefer to don for important stuff? Feel free to post a screenshot, if desired. But only if desired. Don't force it.
