-wyi
Wyi's cryopack, keeps him from overheating.
In some "canons"(RPs, stories, timelines, etc), generally the ones where he's not on copper-9, it can release a freezing cryo-blast, which immediately freezes anything nearby. (doesn't coat in ice, just puts in sub-zero temperatures, like throwing liquid nitrogen).
It is just a mostly normal backpack that he edited, shoving a high-tech cooling system into, and cutting some parts.
it holds tools and stuff, like his car keys (of course the window on the car is broken so it doesn't matter), a note book/personal log, and his laptop and transmitter.
If it is broken and he's in a frozen environment, he will generally have up to the better part of 10 minutes before things really start to go wrong.
the bag is not extra-fortified, but the mechanical and electronic pieces are, with heat-conductive padding (superfine copper wool) to keep them from taking too much damage.
It also has anti-emp measures, so that no one can just use one to break it.
