I bought the men's because of my hip/waist ratio (women's waist sizing is always too tight) so I can't comment on size. But the waist is very high which I love so I can tuck all other layers in. I love the wind stopper fabric. It's not stretchy but the inserts do a good job for that. I've worn these tights over a base layer for running on windy and freezing days (30 degrees today). They're great! And look different/sharp, I think :)
I ordered a Medium and had at least 6 inches of gap in the waistband, which is Not elastic (i.e adjustable). I am short, and I must surmise these are made for average to tall women, and those that have small hips so they can order a size where the waist band won't be so huge.
Great product for cold weather running or biking. Kept me warm and dry while running in a light sprinkle. I didn't even feel cold, or hot for that matter.
I was right between a small and a medium. Went for the little bigger size. The legs of the small would have been too tight. Had a hard time keeping the waist up and the legs didn't move easily, had to keep pulling them up. If you can get them to fit a little better they are a great product.
