We noticed these and decided we needed to up our drinking game.
If you are on American side of the pond, you would call these a pint. For those of us in the UK, we would say 473ml, which is a bit less than a pint.
A decent size to hold and able to fit in most cup holders, these will ensure you have high quality materials for the drinks you have around camp and on the road.
They are stackable, easy clean and if you are using them at home, they are dishwasher safe too. We wouldn’t recommend hot drinks for these as they are not insulated, but we do recommend beer, wine, milk, juice. You don’t have to carry those plastic ones anymore, you can let everyone know you mean business with your drinking.
