Mountain Hardwear Men's Micro Grid Zip T

Great fleece for all conditions
This has become one of my favorites. It's well made , very comfortable and perfect either as a mid layer or under a shell. I am 5'11" and about 165 lbs, and the Large was snug. I prefer a little looser fit, so a XL works better for me.

Versatile Performance
This is a great top to wear on its own during shoulder seasons and as a top or intermediate layer in the colder months. Well constructed, extremely comfortable, and it's built to last! The quarter zip is one of my favorites, and the left chest pocket is perfect for the iPhone or similar mobile device.

Excellent
Just got this and it's one of the best fleece tops I have, fits perfectly. However, order 1 size up, I usually ware medium but large fits just right.

Great top, but it runs small
I'm 6'1" and 180lbs and usually wear a M in Mountain Hardware products. Reading the reviews, I decided to order a L. It was a wise decision because a M would have been way too small. The arm length is a little shorter as well - strange sizing. Consider this top slim-fitting and adjust accordingly. Made with lighter material, it's a great top for running if you wear a capilene tee beneath it.

Good fleece shirt
The material of the shirt is very good. It's light weight but warm. The grid pattern feels pretty comfortable. The problem is that this shirt runs a little small than usually, but not quite. You should pay attention to the size. I am 6 and about 175 lbs. L is just a little small for me.
