Geez, I forgot my woobie!!! And, thats something I use ALL the time! Mine was purchased in 1988-when I was stationed at Ft. Lewis. It has gone literally everywhere with me! It currently resides on my couch-I cannot bear to get rid of it.
FYI, Kifaru makes a "woobie" as well-I use one for camping (in warm weather). Its good down to about 40* or so-my original one barely gets the chill out in cool weather, its so used
