Silicone/Collapsible water bottles for wine?

[Wineuncorkeduk]

I came across an advert for a temporary wine holder that is basically a rebranded collapsible water bottle for use on picnics etc. So you fill it up from your usual bought bottle of wine and take it with you. The advantage being it is light weight but also flat pack when not in use. It has a plastic screwcap.

I wondered if anyone had experimented with these as an alternative to other types of wine bottles - glass or plastic?

I have never heard of them but is bringing home a couple of empty plastic wine bottles such a hassle that it needs a solution like this?

For larger amounts of wine 3 litre etc you can buy bag in a box.
