Arcteryx RHO AR Zip Neck - Men's:  The Arc’teryx Rho AR zip neck for men is a great trim fitting base to mid layer.  It is constructed with Polartec Power Stretch to keep it fitting next to skin and to offer tons of warmth for colder conditions.  Did I mention the laminated stash pocket for lip balm, a pack of gum or that lucky ladies business card? Breathable, moisture-wicking, insulated jersey with collar zip to aid with temperature regulation.

Arc'teryx Rho AR Zip Neck Reviews:


yep I am diggin the the super stretchy in all directions newly cut RHO AR. Correct me if I am wrong...this version seems a bit less boxy and more comforming than the previous addition that had been around forever. I am 5'11 165lbs and 33"waist. My sleeve length when buying dress shirts is 35" and a 16" neck is a touch big but comfy. This AR in a medium is perfect. Super soft feel. Great for colder days on the hill as a base layer

I knew this pullover was going to be worth the money. The construction and design that went into this zip-up is exceptional. Arc'teryx pays amazing attention to detail. I purchased the small and it fits perfect on me. I am about 6' 0" 160lbs for your reference. I will definitely purchase another color in the near future.

Another comfortable Arc-teyx piece. This one is not communist Chinese made, but made in El Salvador. I'm 5'10" 155-lbs. Med works for me as a mid-layer.
