Any item or catalog number that I can use to look up the outside dimensions? I wasn’t to know if this will fit in my lunch box.
I dug around a bit and entered “Zak! Designs Insulated Growler” for my search, and found what appears to be the dimensions for the shorter, chubby-looking 32 oz one - 8.75 x 5.5.
That description mentioned the dimensions but not the capacity, however in a different page, I found the 64 oz model listed as 12 x 5.5, so that seems to match with what Woot has provided.
It looks like a good deal here, as the the prices I found ranged from $46 to $60. BUT if you need it to fit your lunchbox, please check it out to be sure… I don’t want you to blame me if it doesn’t fit! 
You must be quite a tracker in real life. I looked and couldn’t get close to that. I trust your findings. It won’t fit my lunch box. I ended up snagging the 32oz. Yeti’s that were available just before the wootoff, though I would have grabbed these, too, if they fit. I do appreciate you looking that up for me. I tip my hat to a more superior researcher.
Will these hold pressure?
I have the 64oz bottle and it doesn’t hold pressure well. I used it for beer a few times and could never get the bottom gasket to completely seal despite cranking it to near breaking point. It’s a thick gasket too so it develops beer stink quickly and will need to be completely removed and boiled clean. My 64oz has since been retired to ice water use only which has been great.
Does anyone know if these growlers are labeled with the capacity? Breweries in my area will only fill growlers that have the capacity labeled on them.
The one that I received does have the capacity listed, 32 oz / 946ml.
Just got it yesterday, filled it with ice to see the results. It seems pretty nice, might get another.
