Atom Hoody Women's

So I had an Atom LT in the early 2000's, which is long gone now, and an Atom AR for the past 4-5 years. They were both fantastic aside from the zipper on the LT as it aged and the shallower pockets compared to other brands. Both faded a bit with usage and the AR got a good snag or two that I had sewed up. I decided it was time to replace my current AR since the Alpenglow colour caught my eye. My thoughts for the current version are that the sizing is better for more layering underneath, the zip pockets are a bit better sized/deeper and the hood is a bit larger for helmets. However, I am disappointed with the chosen insulation thickness for the base model Atom. The AR is/was infinitely warmer. Even the LT, on which this seems to be based since it has the side panels, was warmer. My arms have been cold and it feels very thin. It really needs more loft. I thought they changed the insulation because the old stuff would pack down over the years and this newer insulation would maintain itself, but the salesperson told me that's not why they changed it. It seems less breathable - does anyone else concur? My husband has an SL and the revised Atom seems like a compromise between the former LT and SL. Compared to my The North Face Ventrix (3 or 4 years old), it is definitely leaner on the insulation, and heavier on the price point. I haven't worn it enough to put it through its paces. haven't done anything high output to truly test the breathability. I haven't yet worn it on a blowing snow day or in rain. I am anticipating it will be a valuable piece in my arsenal through spring-summer-fall, just not in winter.
