What Customers Are Saying

The SmartWool NTS Base Layer strikes the perfect balance between comfort and quality.

The fabric is very breathable. Even in warm conditions you can wear this base layer and still feel comfortable. The zipper is also a great addition so you can unzip the shirt in order to keep from overheating.

This base layer does not dry as quickly as some other base layers do. It is thick and it is made from wool so when it gets wet it tends to retain the moisture, which can be quite uncomfortable.

Even though the SmartWool NTS Mid 250 Zip tends to dry more slowly than some of the competitors, it still manages to keep you warm, even if it gets wet. Many other options lose their insulating ability once they are wet.

Almost all customers report satisfaction with this product. I am sure you will be just as pleased if you try this great base layer out.
