I've used ponchos in the past, I liked the freedom of movement and the built in venting of sorts they provided, but my feet and lower legs always got wet, so that's why i'm looking at getting a pants/coat combo.

Last year at scout camp, I "made do" with the rain gear I had on hand, a bright orange pullover nylon (I think) jacket I had bought from the local University bookstore on clearance. I thought it was a waterproof rain jacket at the time for some reason. I also had a non-matching pair of red waterproof (or so I thought) pants. During the week we experienced a downpour, my "making do" rain gear left me soaked. Luckily that was the only incident during the week, but I'd like to get a better set of dedicated rain gear before summer camp. Keeping dry (relatively anyway) top to bottom while going from tent to tent to check up on the boys is a definite feature I am looking for, but after seeing all the great suggestions, now I'm thinking something vented or breathable would be a plus too. I'm not hugely tall, a tad over 6', but my arms are long and lanky and sleeve length is usually an issue on regular sized items, so I like to get tall sizes whenever available.

Anyway, thanks for all the replies, if anyone has more suggestions they would be greatly appreciated.
