Core Concept Old Faithful
I've owned the Core Concept Old Faithful midlayer for three seasons now, and it's still going strong. Made of Polartec Power dry, this shirt wicks moisture away in order to keep you warm and dry. A great long sleeve for anything from mountain biking, to running in the colder seasons. Oh yeah, it's also a product made in the USA, by a Boise based company.
How's that for supporting local?
