I agree with "readimag", I tend to lean towards the high end mountaineering gear. I've been riding Arcteryx or Marmot for the last 15-20 years and swear by it. It depends on your conditions, up here in the PNW (Baker/Stevens) you need killer gore-tex. It aint cheap ($1100 bucks for shell,bibs and gloves), but you get stuff that is bombproof. I have the Sidewinder shell and some older Minuteman bibs.
If I didnt ride with Arcteryx or Marmot, I'd look at the higher end Burton AK stuff (I own a pair of their AK pants), a couple buddies have the AK stuff and love it, plus it has a lifetime warranty
Hope this helped
