Review on Smartwool Mens Merino Sport Sleeve T-Shirts & Tanks: Top-Quality Men's Clothing by Brandon Daughenbaugh

I can write a review about it in early September because I used it in a trail race in the Alps around Mont Blanc at the end of August. While the temperature wasn't too cold during the race, it dropped enough to justify wearing this jersey. It also met one of the equipment requirements without being bulky or heavy. I chose it because the front zip would allow for some "thermostat" level control, and I was happy to know that I could tuck in the sleeves to the elbow for added control. These two adjustments allowed me to wear it when the temperature was warmer than I could wear with the zip closed and sleeves down, so its effective temperature range was wider. Overall it's quite comfortable and works great as part of a layering system, although I only wore it alone and under a light rain jacket during the race.
