We BBQ a lot in the warmer months and like to have a few cocktails while doing it. The nice thing about these glasses is that they are completely shatterproof. We have had a few issues over the years with accidentally knocking glasses off tables outside.
The glass is 12 oz, I think for highballs I really should have got the 14 or 16 oz but that is just a personal drink size preference. The bottoms are a little funky as they are footed. It gives the glass a different more glass like look but I'm not sure I like that for stability of the glass long term.
Overall a good glass that you won't worry about taking outside with you this BBQ season.
