I had to exchange the large for a medium. I'm small in da bass. No problem the Co. sent the the med. it's great, perfect. I will wear on cold days around town.The main purpose is just what the copy says .To take off the snow pants, mine are not Downhill Mascara Mt. look cute, they are for snowshoing at over 10,380 feet, breaking trail .They come off as soon as I'm through and now I have this skirt to put on over the tights to go to lunch or whatever the next activity might be usually it's food. Exercising at that altitude is cardio in the extreme. Be prepared, this is the real outdoors. Get there before the lifts open bliss out. Love my new skirt. .
