Looks like a pretty nice set of drawers...
My son swears by the Sitka patterns, but he's pretty big on the ASAT patterns as well. Where he lives now (SE Utah), there are plenty of opportunities for him to use about anything.
For drawers, I have three that I rely on... One is a soft, brushed cotton (don't ask me what camo pattern it is) for warmer weather - say down to 30*F or so. A second pair is in the Cabelas Outfitter pattern with some kind of miracle wool/synthetic blend, and those are good for temps down to around 0*F - colder if I wear long johns. And, the third set of drawers is a heavyweight wool surplus pant (Swedish, I reckon) that is a solid green. Those stay tucked away until it is definitely sub-zero for the whole day.
Gotta' admit, if I wasn't such a tite-wad, I reckon that ASAT stuff would be a top choice for me as well.
