Arcteryx base layers: Rho AR
In the previous post we went over the Arcteryx Rho LT, a lightweight, though some refer to it as a midweight, base layer. And now, it is a turn for its heavyweight cousin – the Arcteryx Rho AR. What stands behind this fancy name? Polartec Power Stretch.
Arcteryx Rho AR Base Layer
And in case if you have never come across this fabric, Power Stretch is a body-hugging 4-way stretch body material. In my opinion, this particular model has an athletic fit and so you should consider sizing up if you intend to use over a light weight base layer. For example, I almost suffocated when I tried this layer (size L) over my Rho LT (size L).
I would also suggest using the Arc’teryx Rho AR as a mid-layer and not as a base. I personally do not think that this particular material is the best option to wick moisture from your skin. In my opinion, it is an insulating layer best used when things get nasty and you want to keep your core warm.
As it usually a case with Arcteryx gear, the Rho AR is an exceptionally well made item. It also has a very attractive design and color combinations, something that is often missing with similar products manufactured by other companies. But if you are not particular what you wear, a $40 power stretch fleece from a less famous manufacturer should perform equally well.
Disclosure: I bought my AR for around $65 on sale. My second power stretch fleece was manufactured by backcountry.com and cost less than $40. To be honest, I can barely see any difference in performance. One just fits better than the other.
