The AMK bivy bag was quite big, too big to fit into my PSK so I have to go with their emergency blanket instead.

I don't know how different hockey tape is from sports tape, but they sounds similar. It's a thin fabric tape that's soft and flexible (not stretchable), water resistant, stick to skin quite well, add traction to stuff, overall quite a few uses. But I probably don't need the whole roll, so maybe I can make a smaller one.

The spare cell is actually for the light in 1st row so no tools needed.
