Good. Not perfect.
- Familiarity: I've put it through the wringer
Let me preface this by saying that I love SmartWool. The only issue I have with it is that SmartWool just doesn't seem as durable as the other leading brands of merino clothing, except when it comes to socks.
The NTS Lightweight Top has all the great properties of merino. It wicks well, keeps me warm when wet, and doesn't stink. My only issue is that it started to get holes almost immediately and hasn't held up.
