    Good weight fabric, not see through like some. Great for low odour clothing in summer. Good length. Hugs my generous waist a little too much but very happy with the t shirt

    I like this shirt a lot and have worn it several times in just a few weeks. The fit is flattering. I am 5'9" and the length is long enough as well. I got the large. I would recommend, especially for merino at this price.

    This shirt feels like a well worn cotton shirt - very soft. wish it were just a little thicker, though. Great next-to-the-skin base layer.

    Very nice shirt, especially for the price. Runs a full size big, though. I wear a M or L depending on the cut, got a L because there weren't any Ms available, and it fit like an XL. This was easily rectified by throwing it in the dryer once, and now it's one of my favorite shirts.

    I wear a medium in ice breaker and smartwool (32E), but the medium in this was quite baggy in the waist. It is definitely not as fitted as I would have expected. I will try to exchange for a small. I liked the dark purple color - bright but not quite fluorescent grape. I plan to wear for traveling, and it seems like it would wash well in the sink and dry overnight like other merino. the scoop neck just manages to avoid showing my cleavage.

    Very soft wool. Great fit. 5'6" 160 and the small fits perfect. Wish they were availible in more colors and I would buy more.

    Puts out a lot of warm for its minimal size. It looks like it would not keep you warm, but warn right against your skin, it is very slight in size and feels warm.

    This is a great base layer shirt for under long sleeve tops or with a vest while running. Super soft and very comfortable! I am very happy with it.

    Works great with shirt. So soft & comfortable. Just wish I had gotten one with a zipper before all gone. Have the short sleeve as well.
