I ordered the XS based on the size chart online (the product is not available in store in Canada). It fits very large and the legs are very wide and the fit of this product is obviously for someone who is curvy. The pants are very baggy on me in spite of being "XS". I would need a XXS. The legs are straight cut and very wide - not good for mountaineering where catching your crampon on your pants leg can be fatal if you trip. There is no way to adjust (ie a zipper or snap that would make it a slimmer profile). There is no articulation at the knees, which would be a great feature, given all of the extra material that one has to contend with. A well made product, but the material is very stiff and in the cold it is very loud and crinkly when you move. The only redeeming factor in my purchase is that I will use them in extreme cold conditions where I will need to wear more bulky layers underneath to keep my legs warm.
