I still have a glorious 49ers cardigan, but it's a bid old and some of the strings are pulling. I love it still. Sadly, it's no longer really sold anywhere, but this was it:

The other sad thing is that I don't really wear sweaters. I'm a naturally warm person in that regard, and being from SoCal doesn't help in the "need to wear a sweater" department.
