Well, my fleece pants arrived. They're just about exactly what I've been hoping for. They're done in Polartec 200 -- the plush, warm stuff of such garments as the ubiquitous North Face Denali -- and the full side zips are done with pretty rugged zippers (teeth, not coils, and one gauge down from what you'd expect in a traditional heavy duty parka). The only minus I note is the absence of draft flaps - but NBD because they'll be under a shell. There's enough volume in the legs to go over a base layer plus hiking pants if necessary, which is what I'd typically have on under my shell when arriving at camp in zero degree conditions.
They come with really terrific suspenders as well -- 2" wide elastic straps and very secure plastic buckles. Also, the fly is super-long, pretty much reaching the absolute bottom of the crotch.
Weight for this size ("medium"/"long" inseam): 18oz
In short, expectations heartily exceeded for this $15* purchase -- I would willingly have spent up to $100 for this as I've been looking for years for something like it, had I found it somewhere ahead of Remix's thoughtful alert!
Sizing: I'm a 32-ish waist with a somewhat more robust rump, and the pants fit very nicely. I think anyone in the 32-24 range would be happy with this "medium" waist size. I ordered "long", and they came with a 29" inseam. Were these street pants, that wouldn't be long enough for me -- but it's just about perfect for use in conjunction with high top boots or camp booties.
Thanks again for the thoughtful heads-up, Remix -- I cant wait to deploy these pants!

* I also got charged a $6 shipping fee that my coupon code was supposed to eliminate -- they've promised a refund, but unless/until that comes through, it's a $21 purchase...
