Thank you Yeti for making a women's MTB short that fits and functions properly!
The thigh opening is narrow enough and the fit is tight enough to not get caught up on the seat when getting on and off the bike (maddening) but they don't constrict movement either. The length is flattering, and long enough to cover the awkward knee pad gap and the material is perfect thickness + I love the Yeti turquoise!
For reference I'm 5'9", 135 and the S fit perfect. I am elated to be free of my baggy, dumpy butt NF shorts!
