Filson baseball cap/hat for sale in color Otter Green. It is in good, but in previously worn condition. It has some patina to it. Its a heavier weight cotton, but I don't think it is a tin cloth, but maybe a twill. It doesn't feel like it is waxed either. See pictures of actual hat to evaluate. It's a very nice hat, and I haven't seen one with this patch before, not that it is rare, but just rare to me...
