Here is a more refined animation of my body scan "deconstruction". My best estimation of the body shape underneath the gear. As MrsPC has pointed out, there are two areas where the subject could be heavier - the upper torso and the outer thigh. I spent this week researching pouch pocket tactical vests and pouch pocket tactical cargo pants, and have concluded that
if the subject is heavier in those two places, it cannot be substantially, due to the pouch pockets. The red dots in the animation represent data points of the narrowest diameter of the body part. On the soft bulk, those data points are
confirmed. On the firm bulk (shoes, helmet, pouch pockets), those data points are
based on measured thicknesses in similar items. The red lines represent the euclidian distance applied to standard human anatomy.
Despite appearances, it's my experienced opinion that the subject can be
thinner than the animation represents, but not substantially heavier:
