I think you may be misreading their webpage. I take it to mean that Acumen is the manufacturer making jackets for Crux to Crux's specifications using Pajak's down. I'm unaware of the same jackets as the Crux ones available elsewhere.Not sure but they seem to just "brand up" other manufactures items
You can tell the amount of down in the bags from their name. But I'm unaware of anyone finding out the amount of fill in a jacket.Yes, I specified my last bag and they were super helpful.
I don't believe that I'm obsessed with price, but I do like to know what I'm getting for my money.everyone on here is *obsessed* with price...the *cost* of an item
