I’ve tried many, they all have their pros and cons as far as I can tell
I think Kastels are the most comfortable, especially in extremely hot weather. They seem to cool the best and they feel the softest and most lightweight to me. I don’t love the logo and a lot of the color options. They often can be found on sale so I would be hesitant to pay full price.
The Tailored Sportsmans are ok- they have some fun colors and they look nice but I don’t find mine to be quite as cooling as the other shirts I have. I wouldn’t wear it on super hot days but it’s nice for when the weather in is in the mid 70s or so. I only have one and have no desire to buy one again. They are pretty soft to the touch though as well.
Swing Bette and Court- I really like my Swing shirts, it’s very similar to the EIS but can be found cheaper. It feels very slightly heavier than my EIS but also seems like it will hold up better. There are lots of good color options as well.
EIS- I really like the EIS shirts that I have but I have never paid full price for one. They are very slightly lighter and cooler than some of the cheaper ones but I haven’t found it makes enough of a difference for the price.
Irideon- For the money, these are some of my favorites. They can pretty easily be found for about 40 and I think they look really nice and do a good job keeping me cool. There are not many color options.
Dover Coolblast- If you can find them on sale they are pretty good for the money as well. I’m not sure I’d pay full list price for another one but they seem to go on sale for around the $50 mark- at least certain sizes and colors- and I would consider getting another one at that price.
I think if I had to rank them I would say
- EIS
- Kastel
- Swing
- Irideon
- Dover
- Tailored Sportsman
Kastel is the coolest, Irideon is the best value, EIS has the best color options and fit.
There are obviously other options I haven’t tried as well and I’m curious to see how others would review some of them.
