I totally agree with the front and back articulation, but coming from someone stuck in this particular fiberglass cage, side articulation is a must. When I look at the armor, I think that the armor does have full compression articulation on the whole midsection of the armor. I mean, it's only logical.
Oh, and I can't wait to build this suit. It'll be so much more comfortable than my current one
Keep up the good work!
