Cosmoterran

I ordered minutes before the Tier One deadline expired and received mine a couple weeks ago (three, one each for a friend, my brother, and me). I unboxed it today at my friend's house, where we'll construct the kits. I'm disappointed that I have to put the helmet on by turning it sideways until it's around my head. I may buy a larger helmet from another manufacturer; which would be best? This is my first time building armor.
