Perhaps different than those of you flying in urban areas, but being based in Alaska, there are different considerations. "Surviving the crash" is a two part deal -- after you reach the ground, and survive the crash, you may need to survive until help arrives. That means wearing clothing that not only won't burn, but will allow you to not freeze to death after the fire is out. Clothing and equipment worn on your person is survival gear, while clothing and gear carried in the ship should be considered camping gear, since it may or may not be available after a crash.
While I am in the lower 48 now, it was -38 F today, mid-day, at Port Alsworth, Alaska, near where I did a lot of flying over the last year.
