When the cold turns serious, the Arc'teryx Rho SV Women's Bottom brings the warmest base layer protection in the Rho range to your legs. A heavier fleece construction adds substantial warmth while keeping the soft, next-to-skin comfort and moisture management you need for active days. It is the deep-winter foundation for legs that feel the chill.

Why we like it:

The extra warmth without added bulk is the win here; it layers under a shell pant just as easily as the lighter Rho but holds more heat. Next-to-skin comfort makes it easy to wear all day.

Features and Functions:

The Rho SV Bottom uses a heavier hollow-core fleece for added warmth with a strong warmth-to-weight ratio and recycled content. The next-to-skin fit speeds moisture transfer and traps heat efficiently, while smart patterning and a comfortable waist keep it easy to layer through long, cold days.

Fit and Sizing:

A next-to-skin fit aids thermal efficiency and layers cleanly under ski pants. True to size, with a snug fit that maximizes thermal efficiency.

Bottom Line:

For severe cold and high-output winter days, the Rho SV Bottom is best at maximum base-layer leg warmth that still breathes. The warmer option when the standard Rho is not enough.
