Pretty neat design. I wager a suit like this is intended for quick transfers between ships or for very short EVA missions (like for retrieving experiments placed outside). I think placing the primary live support line's input in the helmet is a bit off-putting from a design standpoint. It obstructs the view of an astronaut if they're working with their hands. If it was connecting to the back of the helmet it would be better, I'd think.
Although if again this suit was designed more for an astronaut to be mobile in space, the design is a good "quick walk" setup.
