I used this shirt for a specific 5 hour hike in New Zealand. At some point it started to rain, a layer of fog settled on the mountain and the weather turned bad, but I was never cold. This base layer kept me warm, comfortable and generally pretty dry. I would 100% recommend this base layer to anyone looking for a cheap alternative to what Nike, Adidas or Under Armor offer. So, if you're looking for a base coat for fall or winter, this is the one you can grab and it should help. For sizing reference, I'm 5'4" and about 135-140 pounds. I bought an S and it fits just right. The seams or the direction of the material/fabric around the arms tend to feel a bit tight, like they're pulling on the rest of the shirt, never mind.
