Ive ordered three pairs of these pants to share between me and my 14 year old daughter. Shes a size 2 and I wear a 14 and some how they work for both of us. They are extremely comfortable and we both love them. We got them for a trip to Guatemala and they were perfect. Cool nights and warm days were no problem. If I could suggest anything it would be to make the pocket just a little bigger. Its good that it zips but its not quite large enough for my regular size iPhone.
