Smartwool Men's Lightweight Zip T

I urge all review-readers: as always, shop around. I saw this top for as much as $80, but with a few Google searches found it for $30 on clearance.

Unlike the previous reviewer, I found the sizing chart to provide a good fit (I'm a small). I've been favorably impressed with this shirt. I did expect it to provide a bit more warmth, however.

To give a better idea, I'm a hot person in general and frequently hike with this as my shirt in 60ish degree weather with a 28lb pack with no problems. I would roast alive if I tried that with a long-sleeved shirt with any kind of insulation. Don't expect it to give you much insulation.

The wicking is awesome. I sweat a lot, even if I'm properly dressed, and I have not noticed wetness at all with this shirt.

It is also more durable than I expected. I did a weekend of bushwhacking through some tough underbrush this last weekend which shredded some of my gear, including the RidgeRest I had strapped to the outside of my pack. The shirt came through unscathed.

Bottom line: this shirt is awesome, but I wouldn't buy it at $80. Look around for a better deal.

This is supposed to be a either a baselayer or midlayer shirt that would do well in sports. I found the sizing terrible and uninteresting.

Pros:
Quality Merino
Flat seams

Cons:
Baggy and sized poorly with too long of length and misplaced shoulder seams for a size small

If you don't mind using it as the best sleepwear ever, which is what I've adopted it for, then intend it to serve similar purposes. This is a far cry from being an athletic shirt.
