I just wanted to corroborate what I've been reading about the Peak Elite AC, which is that people are reporting it actually weighs LESS than what POE claims. My girlfriend just got the women's version (5'6", more insulation for the feet) and it clocks in at 11.1 ounces on the scale, much less than the 15 oz claimed. For anybody who is shopping according to weight this might change things for you. I personally was going to get the neoair all season at 19oz but now I think I'll get one of these. I wish I knew whether these are lighter because they have been altered from spec in some way, but I suppose we'll find out if it is as warm as they say.
