Summary
The Arc'teryx Rho LT Bottoms are a fleece-lined, durable base layer that works well as a standalone layer or under shell pants in cool to cold weather. They deliver warmth, excellent durability, and strong wicking with comfortable, stretchy fit, and true-to-size comfort, though high water absorption when wet and long leg length can be drawbacks; ventilation is important to prevent clamminess in heavy sweat.
