Ben M.wrote a review of Arc'teryx Rho AR Bottom - Men's on January 17, 2016
Familiarity: I've used it once or twice and have initial impressions
Fit: Runs large
Got these for those sub zero days. So far they are very warm in temps down to -15. Got the large size as thats what I usually wear but I think the medium would have been a better fit for me in these. Thought about returning them but size medium is/was out of stock. Arcteryx sizing seems to run all over the board for me.
