I purchased this new at a Lowell Spinners game. Rare in the U.K. can't believe many people have brought one back from the U.S. The Spinners are a Minor League team, in the New England area, and their merchandise may only be available at the stadium I've tried it on but I can't ever remember wearing it out. Although it's a small/medium it's a stretch fit so will be ok for most people, I'm usually a 58 or large in hats and it's okay for me. If you want any more information please contact me. Thanks.
