Cold days and long approaches call for a baselayer that breathes as hard as you do, and the Arc'teryx Rho Women's Zip Neck delivers. This lightweight fleece base layer top traps warmth, wicks moisture, and vents through a zip-down collar when you heat up. The soft, next-to-skin feel keeps you comfortable through steady efforts in cool to cold temperatures.

Why we like it:

The zip-down collar is the feature you will use constantly; it lets you regulate warmth on the fly without stopping to shed a layer. Chafe-free seams throughout mean you can wear it for hours without noticing them.

Features and Functions:

The Rho Zip Neck is made from a light fleece base layer fabric with excellent moisture management and soft, fleecy comfort against the skin. A zip-down collar regulates extra warmth, chafe-free seams run throughout for long-haul comfort, and the next-to-skin fit ensures efficient heat trapping and wicking on cold-weather efforts.

Fit and Sizing:

A fitted, next-to-skin cut maximizes warmth and moisture transfer and layers cleanly under everything. True to size; the close cut is designed to be worn right against the skin.

Bottom Line:

As the foundation of a cold-weather layering system, the Rho Zip Neck is best at active warmth for skiing, touring, and winter hiking. A breathable, hardworking base for steady output in the cold.
