Get one for yourself, your friends, and family!
I wear a Large, so couldn't get one for myself, but got two XLs for my brother-in-law and my dad.
My wife gave the one to my BIL the other day when she went to see my sister.
He called me and said "Is this a birthday gift (it was in July!), a Christmas gift, or a just-cause-you-like-me gift?"
They do make great gifts!
