The recent thread about the fire in the high rise and this article got me to thinking:

I've been considering adding a smoke hood to my Urban EDC, since I spend my working days in subways and high rises. Anyone have any experience with these? I see they range in price from $40 to $100+, and I would have to buy one for each member of the family so it could get pricy. Any input appreciated.
