High quality, great value, superb sun protection
This is a very nice shirt. It’s the newest version of a shirt that was already great. I have owned several of these over the years and say with confidence that they are high quality and very good value for money. I have worn them all over the world, trekking in the Himalayas, trail running in the alps, and running and rafting in the Grand Canyon. I am very careful to always cover up as much as possible when out in the sun, even more so when it’s blazing hot and the sun is at its max, and these shirts do a fabulous job of both sun protection and keeping me cool. I also wear this shirt on cool, rainy days, or early morning runs. When I get sweaty, it does a good job of wicking away the moisture. I’m not sure when they started adding the thumb loops to this shirt, but I appreciate it. It helps keep the sleeve in place and gives added protection for my wrists. The sizing is relaxed but not so much to be sloppy.
Excellent first layer.
Tested this shirt the day after purchase and it performed wonderfully. Started the hike with this shirt as first layer, with a lightweight REI fleece as over layer. Temp was 50F, and was neither cold nor too warm with this combination. As the temps climbed (as did we), removed the fleece and wore only this shirt. It wicked away sweat, and remained pretty much dry the whole 4.5 mile hike, then dried quickly at hike’s end. SPF rating for this shirt is 50+, and provided ample protection from the very bright sun that day. At approx 1/2 the price of other brands, this is a great deal for the money.
