Reddit mentions of FROGG TOGGS Men's Ultra-Lite2 Waterproof Breathable Protective Rain Suit, Khaki, X-Large

I was advised to get a Frogg Toggs Ultra-Lite2 rain suit, and then to bring zero other pants. This was the correct decision (for me). I never once wore the rain suit while moving/hiking -- basically just for in-camp -- but just knowing that I could put those pants on and I'd warm right up was all the mental security I needed. This rain suit also allowed me to carry only a super-light 55 degree sleeping bag, and on the one or two nights when the bag itself wasn't warm enough, I just put on those rain pants and was warm and toasty. (All that said, if you're gonna hit the Whites/Maine in November, you're gonna need something better than a 55 degree bag, but I think shorts and rain pants for emergencies will get you a long way without much weight or complexity.)

I use boot covers and a full frogg toggs set over my regular gear. Both pack up nicely and are a breeze to dry out.
