"Such soft material and fit my partner perfectly even though he often has trouble with sleeve length. Was a great warm base layer for a recent trip."

"Great shirt, great color, works very well from spring to fall."

"For the last 5+ years I have asked my father if there is anything he wants for Christmas, his response; "another one of those tops". As he gets older and feels the cold a little more he wears these year round, to the gym, around the house, when going out, even sleeps in them. One year there was a black with small white stripes color option which would be great to see again."

"Perfect layering weight for winter. I pair it with a 125/150 weight tshirt and it works well under a solid jacket all the way down to 20 degrees. I tend to wash by hand and air dry these items for maximum longevity , but they can and do tolerate a delicate wash cycle."
— Matt S. (5/5)
"Sleeves are long enough! And the fit is great. Love the easy care - machine wash and then I hang to dry. Next-to-skin comfort. I wear as a base layer during the winter months…. which is 6! Up here in northern Ontario (Canada)."
— Erika T. (5/5)
"This was actually a gift for a friend - but I can say that I love this layer so much that I own two of them so I don't over use the one. This is one of my favorite layers I own, it is incredibly versatile."
— Joel O. (5/5)
"Très bonne qualité"
