Canoedogs, I had one of those and didnt care for it at all-I found it too drafty, and the middle slit opened up on me too much (I toss & turn a lot).

I dont know if I have a FAVORITE piece of issue gear, but, I do use a lot of it in my jeep. I have the current issue military sleep system (almost time to take the winter black bag out, yay!), issue poncho, and the Swedish Trangia. All 3 have stood the test of time for me-two were kept when I left the military, so they have been field test, extensively.
