Aluminum will spoil you, Sir Edward...and I have cause to know as I have a butted aluminum hauberk that is a dream to slide on! Like the rest, putting on a steel hauberk requires some acrobatics...it would appear our forebears did the same, judging by some of the period artwork I've seen where knights were bent in half as they pulled on hauberks.
Ulrich, you will want to practice putting it on by yourself- keep at it til you can do it by yourself. Normally, knights had squires to assist with the armoring but we don't, so we must learn to make do.
