Step 1: Helmet
Step 2: Torso
This piece was definitely the most challenging. It covers my whole torso, leaving only holes for the arms and head. However, it was still flexible enough that I could lean side to side and bend without limitations. It also opened along the center of the front so that I could easily step inside and put it on.
