Gave these as a gift and she wrote an in depth review
"I am 5'4" 123 lbs and these pants in size small fit relaxed rather than fitted. The XS was just a little too fitted and size S is a little looser than I prefer, but I think they are supposed to fit more relaxed. They are a little long for me, but most pants are. The velcro waist cinch is a nice feature, BUT with the elastic in the back of the waistband, the pants do not stay put at the waist and I constantly have to yank them up. A belt or suspenders is a must. The waist would fit much better without the elastic. There are more pockets than I can use and I prefer to wear my beacon on my body as it pulls down on the pants when in the beacon pocket. The left thigh pocket is convenient for holding your phone. The waterproof/breathable and stretchy material is top quality and is comfortable for walking and skiing. The side zips are easy to use when I need to loose some heat on the uphill. overall, I would recommend these pants, but with a belt."
