The Teller Tech Tee’s most eye-catching feature are the micro-sized pin holes blended into the fabric for breathability. Under the arms as well as in the main core area, with solid fabric over the arms and lower side areas for durability, they help wick moisture remarkably well.

In terms of fit and other features, the Teller Tech was comfortable, although not form fitting. I really liked the small pocket in the right rear lower section of the, which can easily hold a mobile device, or small iPod with cable routing for headphones. I also liked the main front zipper with a long pull which added to the breathability.

As for actual on-the-trail performance, the combination of 25 percent polyester blended with 75 percent Merino wool may have created the success of fast dry times and wicking and most importantly eliminated odors that I ended up wearing for over 10 days between washings. SmartWool also gets a thumbs up by combining mapping of vent zones as well as utilizing the benefits of adding a synthetic material with the wool that aided in moisture transport as well as durability.
