I'm going to suggest that it not be quite so snug and that it have wrinkles at elbows and knees. There needs to be some air pressure inside to counteract the vacuum of space (IIRC, normal earth atmosphere is 7 pounds/square inch). If he is wearing a helmet, he is either in vacuum or an unbreathable atmosphere, which might have a different air pressure than ours. I'm also going to suggest that it have patch pockets on the upper arms and thighs. If not there, than a tool belt with lots of pockets. Pockets are too necessary for small tools, pen&notepad (PDA), calculator, camera, whatever. You are outside replacing a solar panel... you unbolt the behemoth... where do you put the bolt? You can't just set it down! There's enough nuts adrift in space, and that can be deadly to the next ship to enter the region. You might consider communications... does he have an antennae? Inside the rim of the helmet, perhaps speaker or sipping straw? Meanwhile, I'm glad to see a non-military space explorer-type suit... and want them for the whole family and the cat. :) Carolly
