How would a modern stealth suit be designed using the technologies available to mid XXI century civilization?

EDIT: Question timeframe changed from early XXI to mid-XXI century. Lets say 2040 decade-ish.

You are the engineer in charge for the construction of the latest 's stealth suit.

It should be the best personal cloaking device mid-XXI century tech could deliver. But also must:

1. Be lightweight (maximum 60lbs)
2. Dampen sounds or outright eliminate them
3. Able to eliminate IR (heat) emissions for at least 15 minutes in a 60F/15C temperature and above
4. little to no extra electromagnetic signature (beyond the normal human body's)
5. be no more than a light hindrance on the agent's movements (so no full-body mirrors on both sides, please) - including a basic aikido roll - can be done with a small backpack.

for the cloaking device and other devices, estimate your weight. ALso, explain some of the "science" behind your choices.
