Arc'teryx Rho AR

I purchased this as a stand alone piece for running on brisk days (~10 degrees C). I like the feature of the half zip to regulate temperature during the course of my run. And it fits well and feels comfortable. While this shirt is great and providing warmth and a cozy feel, it does not wick moisture...

This is easily the softest, cosiest lining ever. Like Golden Retriever puppy soft. The only thing that keeps it from being the perfect base layer is the zipper. As others have said, it simply won't stay up. In really cold conditions I wear a gaiter over it but it should be designed to stay zipped on...

Five star product. Great fit, warmth, color. I just had to pull a star because it’s not really a base layer it’s more of a pull over sweater. Great product though, well worth it.

Keep her too hot during hiking. It should add something like Canada Goose`s index to tell consumer which scenario can be wear.

The Rho AR is my first purchase from the brand. The item is described as an expedition weight base layer and aerobics mid layer. My inclination is that this is a mid weight layer and in that regard it exceeds expectations. I would suggest that using this as a base layer for moderate to high energy a...

This is as close to a perfect fleece that I've found, and I've searched long.

The material is super soft and plush. The combination of softness and stretch make it supremely comfortable.

A good collar is essential and the Rho AR delivers. It's a perfect snugness with the aforementioned stretch a...

I love this one especially for sailing in long races (few days on the wavy sea and cold conditions) together with wool base layer or without any base layer at all.

I have found this material perfect for keeping me warm during long hours of inactivity (just staying in cockpit, and sailing for 2 days ...

I have a ton of Arcteryx stuff. Love the clothing they make. I hafta say the Rho AR though is possibly the most unusual piece in my assemblage given how light it feels, yet how crazy warm it it keeps me. I have tons of warm tops made from various poly, cotton, merino fabrics. Some are pretty heavy ...

(This review was collected as part of a promotion.) I've had my Rho AR for close to 10 years now and still consistently wear it in the winter. It is super warm and doesn't get used for half the year.

It has a great trim fit with a lot of taper to the waist, the stretch is nice too. It is a littl...

Being an avid skier/snowboarder, I always like to have a base layer to keep me warm, with minimal layers on top of that when I ride. I have always used hot chili’s brand in the past until my friend turned me on to Arcteryx. This base layer shirt immediately felt a million times warmer, yet had that ...
