My wife doesn't use these anymore so we need to sell. They're very lightly used only around 3-5 times. I'm not sure of the model name but they are very comparable to my first lite rain pants and they were 100% waterproof for my wife. Arcteryx doesn't make things that don't work. Size Small but the sides are adjustable in the waist with different loop options as seen in pics. For reference, my wife has a 27" waist and these fit perfectly. Asking $75
