Own them and Love them.
I hunt pheasants at least every weekend of the entire season. I also hunt a club into March of the year. I beat the crap out of pants and jackets. These bad boys hold up great and keep you dry. People will say that they're heavy or cumbersome. They're no heavier than a pair of overalls and they're no more cumbersome that a pair of long underwear, jeans and chaps.
If you are a twice year guy or if you live in the south, you might not need/want these. If you are a person who is going to hunt into the cold, make an all day push when the weather is in the single digits and snowy/wet, you'll be glad you own them.
To each their own.
