I saw some video of comparitive testing done with the Russian K36 ejection seat in a wind tunnel in the USA using the US helmet and mask and everytime the helmet seemed to come adrift or off. The Russian hemet had small colletted holes in the front of it to relieve this problem and it seemed to work well.
My set of USAF/N/MC nomex flight gloves always seem to cause my skin to itch to!!!
However, I think the current US survival kits in the seats are better than ours.
But what the hell do I know?
