Sorry guys,
I opened a can of worms with some simple advice and a packing list...I think there are too many barracks lawyers who try to find/dig/conjure(sp?) up some sort of magical way to get through SFAS. I won't make that mistake again.
For anyone preparing for SFAS, good luck, do the best you can, and just do it. Follow the guidance from the men here, carry only what is on the packing list, quit trying to find a magical answer that just does NOT exist! If you quit in SFAS, you can't be selected regardless of the type of boots or how many BDU's you have, or your ruck times. The only magical answer I have for you...DON'T QUIT!
