wears great, keeps you warm
I was in subzero windchill with an insulated 3/4 base and the Rho LTW bottom. I was comfy without even thinking about it. As the season ends, I expect to use these as my only base layer. Very comfy and would recommend.

Warm and dry
These Rho LTW are great. I wear them with my soft shell pants. They regulate my temperature very well - warm and dry, not sweaty and hot. I have had issues with wool due to sensitive skin. No issue with these bottoms. Best buy in my opinion.

wool base layer
i use these as a mid layer and they work great,very warm and comfortable,they seem to be well made,as the other reviews said they are a bit long but its not a real issue, another great product from arcteryx

Maximum warmth from a minimal base layer.
The Rho LTW fabric exceeded my expectations for both warmth and wind protection. I own a regular pair of Arcteryx Rho bottoms and the bulk to efficiency ratio can't compare to the Merino LTW Rho. At 6'3", 225lbs and a 36" waist the length was just right on the Large. Excellent buy. I'm now looking for the boot cut length.

Very Comfortable
I uses these when I train outside on cold days. Like the above reviewer said, they are just a little long, though I have that problem with most pants, (I'm 5' 9" wearing the mediums) so I don't consider it to be a problem, they're tights so it's not like they drag on the floor or anything. All in all I'm very happy with this purchase, I bought an additional 2 pair, that's how much I like 'em!
