Alfred Messenger bag

Does anybody know anything about the men's alfred messenger bag? I'm thinking about getting it for my boyfriend for his birthday but I thought I'd ask first if anyone has had experience with it or knew anything about it. Also-- has it recently gone up in price? I could have sworn it was only $4000 six or seven months ago, but now I am finding it for about $5600-$6000 depending on which boutique you call. Does that sound about right?

Thanks!
