This Patagonia Capilene Midweight Zip-Neck Top is everything I needed for a base layer from the thumb loops that don’t feel constricting to the ¼ zipper that dips lower than usual to allow for better airflow. I was also surprised and impressed at how well it wicks sweat without smelling terrible after multiple uses. I will usually wear this base layer paired with a down vest for cross country skiing, hiking, downhill snowboarding or any outdoor activity since it is comfortable and stylish. It’s not skin tight and runs on the boxier side for Patagonia but I wouldn’t want to sacrifice the comfort or ability to move. I want to get the thermal layer now for even colder days!

Great everyday 1/4 zip shirt for skiing or snowboarding. The thermal weight Capilene has the perfect amount of insulation and breathability. The only time I would wear anything heavier than this would be a -20 degree day.

I purchased this to replace a ten year old version of the same thing. I was sad to see the old one go, but the replacement made it ok. Even after all this time Patagonia seems to be holding to their standards and I am as pleased with their new stuff as I am with the gear I have been abusing for a decade. If it's cold and I'm going to be active, I have this on, no question.

Have been using for downhill skiing and like it. Quite warm and comfortable on the slopes. The polygiene is effective. Long zip makes venting quick and is comfortable in the lodge. At home is go-to comfort top.
I'm 5'9" 158 and fit is just right. Color was accurate on the web site.
Two quibbles: as already mentioned the zipper seam base rubs on the chest a bit, but for me not significant. An earlier version of this top (Capilene 4) had longer sleeves which I preferred.

Nice quality, but I don't understand how this can be used as a baselayer. The seam for the zipper is very irritating up against bare skin.

Yes, it's true. This top is without a doubt the warmest, most comfortable thing I've ever put on. I'll go out of my way to wear this whenever possible. It's like wearing a hug. No idea what the other reviewer was talking about. This is designed to be worn under something else. It's insanely soft and feels great, and after you've had it on for a couple of minutes it gets super warm. Absolutly get this thing!!!

I was looking for a heavy weight Capilene 4 level type shirt. Patagonia apparently has changed their rating system so one cannot tell what the heck they mean anymore. This shirt is so lightweight you can hold it up to the light and see right thru it ! Very disappointed.
