Outdoor-grade polar fleece cardigan sweatshirt
Comfortable, soft, and light!
This is how I feel about it!
It is very light in my hand, without any sense of weight
The fabric is a more common soft polar fleece
It is soft,
It feels good to hold it, and it is very warm
The physical feeling after putting it on is self-evident!
Very comfortable!
