All new Purple Grape protective wine bags are the best on the market. We took a look at all the wine bags on the market, improved on them, and designed our own. We use a tough vinyl outer skin, heavy duty protective bubble wrap(twice as thick as some of the other bags) and the best reusable closure on any wine bag.
We put in not one but two separate heavy duty zip-lock closures, a roll tight dry bag end and a Velcro fastener to hold the whole thing securely closed. The bags is large enough to hold most wine bottles or other fragile objects.
Most cruises allow you to bring at least 1 bottles of wine per person on board so take advantage of that and make sure your bottles get on board safely without breaking and ruining all your luggage. With purchase you get 2 wine bags.
