I have two, saving my pennies so I can get the rest of the colors! I wear these for dress up with a nice skirt or pants, to play golf with a skort, for yoga or a weight training class, for cycling, hiking, or just to hang out. I’m sure I’ll also wear them as light layers for skiing and snowshoeing! They’re cool, comfortable, and, at least so far, don’t get stinky regardless of what I’m doing. Lastly, thank you for making them with 3/4 length sleeves - not all of us have the toned arms of our youth so 3/4 length sleeves are much appreciated!
