  • Strategically placed seams increase comfort and reduce chafing
  • Smooth outer-face fabric makes it easy to layer over

    I got this shirt with the intent of using it for backpacking as a long underwear top. I have both in cold and warmer whether and it has worked so well.

    I am 5'10" and athletically built, but with a bigger chest so many top as really snug in that area and i end up having to get the in a size larger but have them really big around my waist. I got a Large in this shirt and it has a really great fit! It fits the female curves so well that i use it a lot for everyday wear as well because it is black and simple.

    When i bought the shirt online i did not realize that there is another fabric that wraps around the arm from the shoulder, but this added detail (I don't know what function is has) makes it more "fun".
