I love these pants! I've been searching for awhile to find convertible hiking pants that are loose enough through the legs to allow for easy, comfortable movement. These pants fit perfectly. I'm 5'3", 115 lbs. and ordered a 4P, which fit loosely (could have fit in a 2P but wanted some extra room). The small drawstring on the inside is very useful and doesn't add bulk.
The first time I wore these we ended up in a torrential downpour. My pants never felt heavy or saturated in the rain, and dried off quickly once the storm was over. And the mud wiped off easily with my hand! The pants moved with me, they weren't restricting in any way. And all the pockets are handy!
I highly recommend these pants!!
