Gem-gum suit

Nanofactories will allow us to make dirt cheap clothing anytime anywhere (even just from airmolecules and sunlight) that give more comfort at any place on earth than any entire house can give today (2014).

Death from freezing will largely be a thing of the past.

comfortable everyday tracksuits

With advanced atomically precise technology clothing can become much more comfortable. First and foremost thermal regulation becomes a thing one just don't have to care about anymore. One can keep the same clothes independent of the whether. This can be archived through advanced thermal regulation as described further below.

With more advanced metamaterials which can emulate elasticity and actively change surface area. Clothing can be made sloppy or skin tight or both on different body parts. Remote sensing for telepresence can become possible too. A simple lightweight hood with transparent visor that behaves like textile when unused and self stiffens when employed can be used to protect the face.

An inflatable mattress for comfortably cushioning sitting or lying that is very tiny in its folded up state can be included. You only need to take care about water and food for the most extreme trips through the land.

Means for washing ones body could be integrated too. This would especially make sense in life supporting protection suits for deadly environments.

If thermal isolation is not too much of an issue suits can be made extremely thinn without risk of rupture and thus maybe barely noticable. This would protect against cuts with kitchen knives and agressive chemicals like acids. This works because of the very high tensile strengths diamondoid metamaterials can have.

Note that the "Fabric" changes area and not shape - that would be utility fog which would be more general purpouse than needed - see:Self limitation for safety.

Temperature regulation

A normally thin skin covering material can blow up a tiny bit in volume and rise it's thermal isolation to levels that suffice for every possible climate one can encounter on earth including -90°C and extreme winds on the polar caps.

Additionally one can use a heat harvesting trick similar to the one penguins use. Turning the sun facing area black (in the visible spectrum that lies way above thermal equilibrium) and the area in the shadow white this maximizes optical absorption while minimizing thermal emission.
(see Kirchhoff's law of thermal radiation, Stefan–Boltzmann law, emissivity and absorptivity)

In hot climate the solar energy can directly be used for cooling with e.g. diamondoid heat pump systems. Physical movement can be tapped as a power source too but depending on the ambient temperature it might heat you up more than it cools you down.

There are limits for temerature regulation. In rather unnatural very hot and dark situations like in a deep mine life supporting protection suits that use energy to actively cool the body become necessary.

life supporting protection suits

Suits for extreme environments like space and deep-sea where no or too little oxygen is present need life support systems which add significant volume and mass. This won't make them exorbitant more expensive than simple AP tracksuits. Only patents and proprietary secrecy may do so when those suits first emerge.

space suits

Space suits can use the same fabric as advanced basic AP tracksuits just fortified to counter (one full nice bar of) air pressure and micrometeorites. Shielding against radiation will always be troublesome.

indoor space suits

Cool would be something like a weightless airspace movement gear.

Suppose you are in a big sports hall far away from the walls not moving at all. You're helplessly stuck there. Its known that air-swimming doesn't work effectively and sucking air in from the front and blowing it back with your lung probably won't be very effective either. You can change our orientation (the direction in which you look) easily by using the cat body rotation trick but that's about all. If you're spinning fast you can't get id of it either.

For mobility in such a situation small round air accelerator plates stiffly mounted to key locations of your body (e.g. at the shoulders hips and feet) would probably work well especially to stop spin. They would only pop up when needed. A wrist mounted winch with a gripper that can be shot towards railings would be more effective for movement towards a wall. The winch cable should be a smart material that breaks in a controlled way when side-ward forces are detected - no decapitation accidents !!

deep sea suits

With diamond as building material deep sea suits will become less bulky. Maybe each finger can be encapsulated seperately. They will still be fairly massive because of the immense pressures. Cable bound telepresence is and will be a good way to work down there.

Telepresence

If the AP suit is suffuiciently equipped with motion sensors it can be used as input device for multi limbed sensory equipped shells possibly located on the other side of the planet. Out in space (e.g. the asteroid belt) the time lag due to the limited speed of light is prohibitive.
