I hunt Wyoming and I've found a poncho in a windy rain storm is not effective. An inexpensive rain jacket of any kind can double as hard shell over your merino layers to keep you warm while glassing. You can probably find a Precip jacket at a good price and it's a handy item to have for any situation. My experience with Frog Togs has been they are loud. Maybe they have improved since I fished with some in Fla.
