This will be a technical manual from what is/is not usable and comfortable.
1. his belt - too low, very uncomfortable when moving
2. grenades - you just won´t reach them, when they are somewhere around the knees.. you must bend
3. magazines - I cant see any. Maybe in bag? Reloading would be suicide for its lenght
4. that big bag on his leg. Try wearing it. Its pain in the ass.
5. Knee caps - why ? doesnt he have this special suit? Plus, he doesnt even wear it properly.
6. that overall - why? doesnt he have this special suit? Low profile maybe, but still there is this helmet that you see in the first place.
Sooo, lets say his suit is bulletproof and he just wants to wear most comfortable equipment he can. First, he should get rid of that belt and get some vest with pouches for magazines, grenades etc. His live but me much easier. Lets say his suit is fire resistant. He should get rid of that overall - why? Its better not that wear anyhing if you dont have to, cause your moving will not be anyhow limited. Othervise, he should zip it up so it has some meaning.
But then... he would never look so cool. So I guess you cant search for logic when talking cyberpunk.
