# Ridge Merino Northwind Merino Fleece Leggings

**Verdict:** A merino-lined fleece tight that Treeline named its best wool option and one of the warmest it tested. It shines in single-digit cold but is too much once temperatures approach 20°F.

- **Best for:** Very cold, calm runs in the single digits °F, for runners who prefer odor-resistant natural fibers.
- **Not for:** Typical 25-40°F winter runs or windy days, since it has no wind panels.
- **Downsides:** Too warm for most winter temperatures; Minimal reflectivity (small logo); Women's only, XS-XL

## What reviewers say

- Best Wool Tights pick. Treeline called it extremely warm, comfortable and odor-resistant, best for single digits or colder, and likely too warm from about 20°F up, which limits its versatility.
