I just saw this on Amazon and purchased it quickly:
AÂ Reusable Foldable Wine Bag for Wine to Go
This non-glass carrier can be taken anywhere glass isn’t allowed. Â It fits a whole wine bottle and comes with a funnel to fill the bag. Â (And it is reusable). Â It is marked down from around $18 to around $9, but just for the next few hours.
So why did I purchase it?
I like to go to places that allow alcohol, like picnics, beaches, hot tubs, pools in certain hotels, etc. Â These places smartly don’t allow glass. Â Someone could get seriously hurt if a broken glass isn’t cleaned up properly!
I’ve used these wine tumblers before in this situation, but they only hold so much.
This is a quick and convenient way to bring enough wine for everyone and drink it in a safe manner. Â Also, it doesn’t have the weight of the glass, so rather than hike with a glass bottle, I think I’m going to switch to hiking to one of these.
Please note from the comments:  “While I like this product and have a similar one myself, this is not really a “huge saleâ€. I bought mine for $4.99 at Nordstrom Rack. And Amazon has many brands for about $10.

Thanks! That’s good to know. The huge plus is it comes with a funnel, but I’m going to use the other ones you linked to when I buy multiple versions (and just use the funnel from the first).
