Anyone wear these as a running tight, or for hiking/backpacking under a pair of shorts? Looking for a combination on backpacking trips that is lighter and more comfortable than shorts + pants. I'm comparing to Arc'teryx Rho AR Boot-Cut Bottom...

Sean, I wear the Icebreaker full length bottom in this same weight to run in and they are the best! MUCH better to run in than any traditional 'running' tight, and I have tried them all. I'm usually between a medium and large and I ordered a medium and they are perfect.

These are as comfortable as they get and super light. I wear as a shorts + Pants combo under a pair of cloudviel run don't walk boxers under my ski pants for very colder conditions (10 to -10). and the comfort is divine. What kind of weather are you be running in?
