At the risk of being naive...what's wrong with the A-3 bag? I did A-10 demo for two years (1992-1993) and stuffed it into a travel pod every weekend. Snagged it on the pod door many times and it survived unscathed. While I don't go TDY as often as I did then, I'm still using the same A-3 bag. It's a bit old and faded but still does what it was designed for. I think it was issued to me during UPT (1984)!
