I use it for wearing the inner mountain climbing low mountain in winter. Because the position of the pocket is easy to use and the lining is fleece, it is shiny. I do not have a collar, zip and cheapest vests are not quite so so if you have a cosa well wearing one, I think you can wear it in various ways. It is a recommended item ^ ^
I wear it in the work clothes every day at this time, but it is very warm and comfortable because the inside is fleece. Because the position of the upper pocket is also relatively high, I think that it is easy to put in and out small items.
