Stellar for warm to hot weather
After some time with this and the short sleeve Altitude tee and the sun hoodie, I'm so impressed with how they perform in hot weather. Some of the coolest material on the skin I've come across in 40 years of backpacking. So breathable!
The odor factor isn't up to merino or alpaca wool level, but those materials are too warm for hot weather, and this does outperform other hot weather material for odor resistance.
Very lightweight also - right up there with some of the lightest material in my gear locker.

My New Favorite Travel T Shirts
I travel a lot and only do carry on. These shirts wash up quick in a hotel sink and are dry and ready to go in the morning. Same on the trail. They weigh almost nothing and take no space.
