AGREED DAVE!!!!!
In really warm weather I usualy wear a pair of cotton camo cargo pants and a long sleeve camo T-shirt!!!!! However.....I usualy tie a wool sweater around my waist just in case I get cold.
I have lots of camo clothing.....I'm a clearance rack JUNKIE!!!!! But.....almost all of it is cotton,with some poly fleece mixed in.
You will almost ALWAYS see me wearing cotton camo cargo pants for several reasons.....1) My legs VERY RARELY ever get cold. 2) They are very comfortable.(next best thing to a pair of blue jeans LOL) 3) They have LOTS of pockets!!!!!
The other thing I buy LOTS of is long sleeve camo T-shirts (XXXL) these are easily put over a wool sweater or two,or they can be worn alone.
Most times when you see me roaming the mountains,or still-hunting the wood lots,I'll be wearing a pair of camo cargo pants and a brown or gray wool sweater
