ARCTIXWomen's Insulated Snow Pants

where is their size chart? Many of the reviewers don't include what their measurements are and what size they purchased. Thanks! (me-12to14. w32 h43)

are they waterproof?

Is this a petite size? I'm 5'5 and a 32 in. inseam would be way too long. I would probably get a large. Anyone know if these were too long?

Do you have any o wear pants underneath or are these wear alone?
