Hey Curtis, the folks at Barefoot International, Inc. are the manufacturers of Fly High Fat Sac's the two of you are referring to. They pretty much can make a fat sac to any dimensions you want, you just have to call and ask. IMO, they are the best and toughest sac on the market. The custom sac's are a bit pricey, but worth it.
