What is the Rho AR?
Soft, stretchy and moisture wicking, the Rho AR is a next to skin baselayer which provides warmth, comfort and thermal regulation for lower output activities in cool temperatures
What is it made of?
Constructed using Polartec Power Stretch, the Rho wicks away sweat and regulates your body temperature, but at the same time provides warmth and comfort when you are out in cold temperatures. Unlike wool, this fabric will also stay warm when wet, so even if it gets drenched in sweat or rain it will retain enough warmth to keep you safe and comfortable. As well as being an excellent piece for regulating temperature the incredibly stretchy fabric is soft next to skin and won't restrict or cause discomfort during all day use.
What are the features?
Flatlock seams add more comfort and remove irritation usually caused by cheaper alternatives, while a tall collar provides extra warmth around your neck. Lastly, the 1/4 length zip allows you to dump heat without removing layers.
How does it fit?
The design of the Rho optimises Arc'teryx's 'next to skin' fit and has articulated patterning and gusseted underarms to add further freedom of movement and less restriction.
Where does it fit in the layering system?
The Rho can either be used as a super warm baselayer or a midweight midlayer. The soft inner fabric and stretchy nature of this piece means it's just as comfortable for both.
