I love these pants! I'm 5'4, 130 lbs and the size small fit me well. The legs are a tad long but don't drag the ground so long as I'm wearing shoes of any sort. I took these on a backpacking trip at the end of October. The weather was still a bit too warm (mid 50s) for the cirque pants but they breathed well so I remained comfortable. Definitely recommend these to anyone looking for flexible yet durable pants!
