I second nearly everyone else who has reviewed these pants in testifying that they are the second most important item in my set of running gear, second only to my shoes. These pants are GREAT. I know they're on the pricey side, but TRUST me, they are worth every penny. My only regret is that I did not invest in a pair sooner. I highly recommend these for the invested/committed runner.
Also, if anyone is wondering what size to get, get the bigger size. I was worried with the size I ordered because I thought they might swallow me up, but when I pulled my pants out of the package, I wanted to cry looking at them because I thought there was NO way I was going to squeeze my 5'10, 140 lb self into them. Even with the large, it looked like my 8 year old cousin might not even fit into them. But when I tried them on, they fit perfectly, like a second layer of skin (if I can say that without sounding gross- I just mean they felt completely comfortable and natural).
Get invested... and respect the distance! Thank you Backcountry!!
