I rarely look to MH for lightweight gear, but this summer in Tuolumne meadows I encountered temps in the low 90's which made my Smartwool Microweight feel rather hot.
Two weeks later on the High Sierra Trail the temps were slightly cooler but I wore the MH Super Wicked Zip-Tee and couldn't be more pleased with its performance.
The shirt was cool, dried quickly and was easy to wash. Even on the steep ascent up Mt. Whitney I never felt overheated. Really, I sweat buckets and it managed the moisture very well.
The only downsides are that it can be a little funky after wearing for a few days, but this can be mitigated by washing it out once in a while. It's also short sleeve so you have to wear sunblock
Overall, a fantastic warm weather activity shirt! Recommended!
