For those that are going to or living in hot climates this summer, I can recommend Arctic Cool shirts. Both my husband and myself ordered a few. The shirts actually get cold when the wearer gets hot. The company is having issues keeping them in stock, and I ended up ordering a couple in colors that weren't my favorite, but I am happy with them. They are well made and fit true to size. I wore one today to exercise and tho I didn't get very hot in order to give it a really good test, I was very comfortable. If you order enough they send you a free cooling towel which I'm excited about for hiking. You'll get 10% off a first order
Hint: I looked on their website and put some tops in my cart planning to return. I ended up getting a 20% off code.
