# Buff Merino Lightweight Neckwear

**Verdict:** Buff's lightest merino tube, which Treeline favors for winter running because wool keeps working when damp instead of freezing up the way some synthetics can. It's thin, so pair it with a hat or headband as temperatures fall.

- **Best for:** Runners who want a breathable, versatile neck and face layer that can double as a headband.
- **Not for:** Very cold or windy runs on its own; a balaclava or Buff's midweight merino is warmer.
- **Downsides:** Thin fabric gives limited warmth; Not windproof

## What reviewers say

- Recommended face and neck layer for high-output winter running; the writer prefers merino because it stays warm and wicks while synthetics can freeze, but notes the fabric is thin and should be paired with a hat or headband when it gets colder. A midweight version is also mentioned.
