I plan to wear it indoors or outdoors in Florida. It is not a heavy warm sweatshirt. Instead this will provide about as much warmth as a long sleeved tee shirt. In cooler weather you could not count on this shirt to keep you really warm like a traditional sweatshirt.
The clothes are very good, no color difference, the size of the purchase is also very fit. The fabric was thick and warm, and there was no pilling after wearing it for some time. No thread, fine workmanship, overall satisfaction of a shopping, will also buy back.
I normally wear an XL shirt, and I ordered a 3XL. I wanted it to be baggy. This jacket was not correctly sized, because it was definitely not baggy. The pockets were farther back to my back than I prefer, and so small I didn't feel comfortable putting anything but my hands in them for fear it would fall out.
