Other than that the mil issue bivy bag works great.
Not the fart sack, I meant the whack-shack...the one man tent. I guess y'all didn't get them issued? I used mine in conjunction with the sleep system in Colorado last November. Worked great.
Looking at the specs it is a little heavier than you wanted, but there are extras you can remove.
