At no time when I was placing the was I informed that there was a larger size.  Once I placed the order I did notice at the bottom of the page, that a larger size was available.  Though I am a large person, but not extraordinary large,I believed that with adjustable side arm would provide a good fit.  Once I opened the packaging and tried them on I found that they barely fit, and were uncomfortably snug.  I truly believe I was ripped off, and will never recommend, and will discourage people from purchasing this product or deal with this company.
