I have the EVAC-U8 smoke hood and I carry it when I'm travelling. I take it out during take offs and landings on the airplane and place it by my bedside in the hotel.
It has raised a few eyebrows on the airplane from other fellow passengers so I jsut explain to them what it is when they ask. <img src="images/graemlins/smirk.gif" alt="" /> Anyway, its about the size of pepsi can and twice as heavy.

Pros are :
small package
hood protects eyes and face from smoke / heat
filters out carbon monoxide (which is the major killer in most fires)
5 year shelf life
If you do use it in an actual emergency , the distributor will replace it for free! (may vary with area)

Cons:
costly compared with goggles and simple mask
needs more space to store
has a shelf life

Consider both options carefully and if it fits your specifications you might want to get one.......<img src="images/graemlins/smile.gif" alt="" />

I had quite a scary experience while on holiday a few years back. There was a fire in the hotel in the middle of the night. I had to evacuate the hotel with my wife and two sleeping kids. I grabbed money and documents and left via the emergency exit and exited into the cold night air! And we were in PJs. Being from the tropics all the time, it didn't occur to me to grab the blankets to keep my kids & wife warm (myself too). We were shivering in the luckily not too cold ( about 10 deg C ) night air. Luckily it was just a small fire and we were back in the rooms in about 1 hour.

Therefore now with hindsight, I have all my stuff in a pack by the bedside together with the smoke hood should it happen again ( Hope not! )
