this is MY suggestion
buy some good neoprene chest waders and a jacket
and wear your regular camo pants over them
warn and DRY and won't get damaged
spent a small fortune on hunting gear over the yrs
dont' care what anyone says, Gore tex gets you wet after a long time in the rain
GOOD rain gear is NOT quiet or felxible
I like you liked that Horse Hide and Saddle cloth stuff(same like deal) was quiet and pretty water proof
called Sport Chief

I think what happened was someone had a patent on the stuff and then others made with without permission, and then it all kinda got pulled!
but was great stuff as far as I was concerned
a company up in Canada used to make real nice stuff too

they changed the name of there material to make things happier and its NOT 100% the same, but close
its just hard to find places that sell it in USA , Cabela's used to carry some of it

but it was my Fav hunting gear, soft quiet and warm,
there archery jacket had a odd zipper design, came across at an angle from a off shoulder, and gave you a hand muff in the middle
which I loved too, then had a pocket above it, making small things like a range finder handy and fast
have a look at them

but I went with wearing neoprene waders under things for really WET hunting, or working outside
can wear again under regular gear
so, that helps save a few bucks??
