Mary K.wrote a review of Arc'teryx RHO AR Bottom - Women's on January 21, 2013
Familiarity: I've used it several times
This warm, soft and comfortable long underwear has successfully acted as an insulating layer to keep my legs cozy underneath my shell in below zero weather!
I skied Big Sky when they temporarily closed the lifts due to below zero which reached double digit values. Even in these conditions, my legs were more than content. I highly recommend the Rho AR Bottoms. I am 5'7"at 126 lbs and the mediums are a good fit for me.
