Built for cool to cold days and lower-output efforts, the Arc'teryx Rho LT Men's Bottom is a performance base layer that manages moisture and adds light warmth. Brushed for softness and treated for long-lasting odor control, it stays comfortable and fresh across long days and multi-day trips. The next-to-skin fit makes it an easy, invisible foundation under any pant.

Why we like it:

The fabric's odor control is the unsung feature; brushed Torrent with Polygiene means you can wear it day after day on a trip without it turning sour. An invisible-zip thigh pocket for your phone is a smart, low-bulk touch.

Features and Functions:

The Rho LT Bottom uses Torrent 190 fabric with Polygiene for moisture management, light warmth, performance stretch, and long-lasting odor control. An asymmetrical elastic waistband, an invisible-zip thigh pocket sized for a phone, flatlock construction, and an articulated gusseted crotch keep it comfortable and mobile through long efforts.

Fit and Sizing:

A next-to-skin fit aids thermal efficiency and moisture transfer and layers cleanly under ski or hiking pants. True to size, with a streamlined fit that hides under any pant.

Bottom Line:

For cool-weather and lower-output winter days, the Rho LT Bottom is best at light, breathable base-layer warmth that stays comfortable from dawn to dusk. A versatile, low-bulk foundation for skiing, hiking, and climbing.
