In the beginning you could wear this T-shirt as a base layer when hiking. However, after wearing it for just one day, I immediately had the feeling that it was for single use only and wouldn't last at all. First, the wool on most T-shirts began to curl and simply deteriorated. Also (as if that wasn't enough) the t-shirt started to smell after the first wear. Being merino it shouldn't smell that bad after a single wear due to its odor resistant properties so I have my doubts about the material it's made from. Definitely they need to seriously improve their quality for me to consider buying again.
