Price will dictate, but I like the various "quad parkas" with bibbed pants/suspenders.  You can get them in blaze orange, but those are basically useless for anything else, so we just wear a (quiet!) blaze orange vest over the top during actual hunting, and can wear the coat or inner jacket at other times.  They will keep you warm down to about zero, especially with polypropylene long johns and good boots.  The Cadillac is Pella brand saddle cloth--quiet, very high quality, and mud/blood/burrs won't stick.  Various others are excellent too.  Cost will be ~$300 (less for Walls brand).  You can also just wear insulated coveralls, but they are a PITA to take a crap while wearing--be careful not to fill the hood with anything while squatting.  Also, don't wear white underwear and peel everything down, revealing white--bad juju in the deer hunting woods.  If you bow hunt make SURE you shoot your bow with whatever you will be wearing.  Many bulky outfits will hit your string while shooting.  Bad thing that.  

Quoted: Columbia Quad Parka

Columbia is virulently anti-gun/anti-hunting and said a big EFFYOO to hunters several years ago.  

Quoted: Quoted: Quoted: Columbia Quad Parka Columbia is virulently anti-gun/anti-hunting and said a big EFFYOO to hunters several years ago.   I call bullshit. Columbia makes HUNTING JACKETS. As in, you have to use a gun to hunt. They also make the premier upland clothing available. When I contacted Columbia about the recent blowup that involved one of their executives and Tim Leatherman endorsing Kerry, they quickly replied and made very clear that Tim Boyle is a strong Bush supporter and that the company itself takes no political stances.

Google is your friend.

This site-- www.saf.org/viewpr.asp?id=19 --contains this quote:

"SAF successfully boycotted Columbia Sportswear several years ago to prevent corporate donations to anti-gun causes, and we expect to win here as gun owners voice their displeasure in Citibank's distrust of law-abiding citizens."

Edit:  This site-- www.freerepublic.com/focus/f-news/1231976/posts --regarding the recent news conference by Leatherman contains this quote:  

Executives attending today's event included: Lee Fromson, president, Cascade Designs, Inc.(Seattle, WA); Peter Bragden, vice president, general counsel, Columbia Sportswear (Portland, Oregon); <snip>

Actions speak louder than words, IMO.  

Quoted: What about Mossy Oak?

Mossy Oak is a brand name of a camouflage pattern.  I'm not sure whether they make their own line of clothing or not.  AFAIK, they license their camo patterns to other companies.  They are excellent by the way--as is Realtree.
