This is my first winter cross country skiing, and I was on the hunt for some pants that would provide more wind/snow protection than warm leggings. These pants are perfect for XC skiing. They block the wind and are water resistant for snow, but still are very breathable. I am normally between a small and medium, and I went with a medium in these. While these are not form-fitting like leggings, they are still somewhat flattering (as flattering as these types of pants can be) yet allow me room to move without feeling restricted. I think the smalls would have been too small.
I also think these pants would be perfect for winter running when it is snowing. I haven't tried them out in those conditions yet though. Highly recommend!

I love these pants! They are the best x-country skiing pants I have, and I have a lot. They are breathable in the back and are super comfortable. I usually wear a lightweight baselayer underneath them, and the combo is perfect in most conditions and temperatures. I am anywhere between a M-XL in bottoms, and the L fits me well. The pants are a little bit big in the waist, but I usually use the draw-string to tie them tighter.

I gave these pants to my wife and this was her feedback: "I love the pants. They're very comfortable. I wore them skiing this past weekend in 20 degree weather... windy and no sun. I wore some leggings underneath and it was perfect. They kept me warm and dry. They are easy to move in and comfortable enough that I wore them all day... even after skiing.

I did not know how much I needed these until I replaced some tattered spandex with these soft-shell pants. They are more flattering than jeans, and more comfortable too. Wind resistant and stylish... take these onto the xc country track, or for a hike... or to go get coffee. They're built to flatter athletic women, and that's worth celebrating! I'm tall-ish, and they reach my ankle - perfect with my ski boots. The BF confirms, these are a WIN (and worth pulling out the camera for!).
