Brian H.wrote a review of Rab Power Stretch Pro Pant - Men's on January 23, 2019
Familiarity: I've used it several times
Fit: True to size
I've uaed power stretch as my warm base layer going back to 2000. There's nothing better, IMO, for anyone who tends to be cold. Super comfortable, super warm and wears extremely well without pilling. I'm replacing a similar pair made by another company after 15 years of three-season use for outdoor activities. . You can pay twice as much from one of the premier manufacturers, but it's the same Polartec fabric.
This Rab version is great, good fit, sound stitching and reasonable price.
