Don't write off those "dress" wool pants !!! They are cheap and they may SAVE YOUR LIFE !!! Who gives a s*%t if someone thinks you're "out of fashion" while hunting in the woods. Those people don't belong in the woods anyway!!! Find some comfortable wool pants and wear them. You can get many different thicknesses of wool pants and one of my favorite styles are the "Goodwill dress" pants. Every once in a while they will have the nice thick stuff too so keep checking and buy the wool!!!while serving in Washington Explorer Search and Rescue it was a time honored rule: "NO COTTON AFTER SEPTEMBER 1st !!!"Deadly HYPOTHERMIA can set in and kill you if you get wet and stay wet with outside temperatures below 50 degrees. Cotton will not "wick" body persperation so it holds it next to your skin keeping you cold robbing you of precious body heat. If you're hunting and outside temps will get near 50 degrees or less lose the cotton... You never know when you may have to spend the night in the woods.I know people probably do it all the time and get away with it but you are playing roulette!propylene, silk and/or wool for thermals is your best bet after September 1st...http://www.dcnr.state.pa.us/forestry/searchandrescue/hypthm.aspxhttp://www.ehow.com/about_4672024_thermal-underwear.html
