They do look very .4'ish to me and I hate to say that it is my least favorite in the zero line. Just hope there is enough interest with these and Oakley's recent willingness to bring back some staples (eyeshade and blades) to do a true repop of the original Zero line, at least in part. Imagine a true subzero #4 Planet X with Sapphire Polarized (ice would have been ideal) or a #6 Planet X with Torch/+ Red?
