Arc'teryx Rho Lightweight Bottom - Men's

These wool bottoms are great. They're not itchy. They wick moisture. And they won't stink after you sweat in them. My only complaint is that they're too big at the bottom and there's excess material below my calf. I love the covert pocket.

Sigh, I think the good people at Arc'Teryx made these bottoms for the starting lineup of the Vancouver Grizzlies. They arrived way too long, even in size small. I had to return them for the Rho Bootcut pair, and even those reach all the way to my ankles. I am fired up about the Rho bottoms though, wool is def the best way to go for insulation.

Very nicely detailed - like all of Arc'teryx products - but let down by a very odd cut. The legs are extraordinarily long relative to the waist.

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.

managed to get the Rho LTW Bottom on the other site but they are amazing. wore for over a week straight on a mt rainer ski tour and i wished i smelled as good as these did by the time i was done. the pocket was a really nice feature for me as most mountianeering snow pants dont have pockets on the sides just zips, so having that little pocket to keep some cash, lighter or whatever dry. they are comfy to lay around the house in as well and keep you surpisingly warm for the thin material. i would rate these as either a light or mid weight. if you're going into the cold i'd suggest these with some fleece pants over and then you should be good for anything the mountians throw at you cheers and beers

Being from Australia and having a kiwi wife makes us big fans of Icebreaker and between us we have about 20 pieces. This time we thought we´d try Acrteryx Merino and we were pleasently surprised. The build quality is typically Arcteryx, second to none and these tights seem a little thicker than my icebreakers. We both stayed warm in Denali's backcountry in mid September. The tops run a little small so DEFINATELY go a size up in tops. Thumbs up all round

I wore these five days skiing at Alta in 20 to 35 degree weather under North Face Pants. They kept me dry and comfortable. The boot cut is perfect. They do not get bunched up in ski socks and boots.

These make for a great base layer, you can't beat merino wool with a touch of lycra. I think these are bit higher quality than the Icebreaker. They hold there shape better after a few days of continuous wear compared to the Icebreaker.

Great baselayer. It keeps you warm and keeps out of your way. The one benefit I always notice with Arc'teryx is that their products work without question, and they look really good doing it! Size down though, I'm a medium and needed a small. They also run long, so keep in mind that they offer the boot cut.

I really like these. They aren't bulky. They keep me warm, but not too. They are comfortable to the point that I forget I have them on. I don't mind the wool, but if you are easily bothered by wool the Rho LT are just as great. Also, you will want to use a 'delicate' detergent for the wool, but you can go long time between washings.
