I bought three of these shirts to take on my honeymoon to Peru and they work great. You want to know about sweat-wicking? They did a great job in the Amazon with sweat and are light weight so not to make you hot. I have also used them to fish for tarpon in this hotter then normal spring we are having here in Florida

After buying this shirt I coudln't wait to try it out. I have been constantly training for a Grand Canyon Hike and have been pushing myself through pretty rough terrains and doing it with a pack. This shirt is not only comfortable, but it does wick sweat even as the temperatures changed from cool to hot. I found the fit comfortable and not binding or tight. The materials used allow air to pass through and keep you cool when you need to be. Overall I'd rate this shirt an 8 of 10. Only downside is that the material is SUPER SUSCEPTIBLE to velcro. My backpack has a few exposed velcro straps and they have to be wrapped up if I wear this shirt. They fray the fabric easily. Aside from that I highly recommend it to anyone who hikes in hot weather. It looks great and feels great. Fit was perfect!

I really like this shirt for heavy exercise like snowshoeing. It wicks away the sweat and stays dry. The sleeves and tails are plenty long. In colder weather it is great under a fleece. Wish I had one of each color!
