Yeah I don't stress too much on if the down is treated as long as it's from a good manufacturer that is not stripping the down of it's natural oils and that they use a good shell material. Others may have better experience on how critical it is, but many of the top manufacturers do not opt to treat their down. Also if you are new to this, make sure you don't skimp on the pad and get one with a good R-Value. Thermarest and Exped are great options.
