Sweaters

I just came across a post on one of the other blogs that I follow - http://theivyleaguelook.blogspot.com/ - that features squash. I do have to admit that I'm a stranger to squash, however, I have played racquet ball in the past and do play tennis semi-regularly.

The point of this post is that the article (http://theivyleaguelook.blogspot.com/2009/07/squash-national-amateur-championship.html) features a gentleman in a great sweater on the left.

I've been looking for one like this for several years now, and was quite fortunate to purchase one similar to this in Europe last year, but the one I purchased does not have a neck cut as deep as this one, to my misfortune. Perhaps someone may be as kind as to point out to me where I can find sweaters in this style?
