Did a 3 day kayaking trip on the Rhode Island coast this weekend and decided to use a couple of the liners that come out of the box wines for a water storage experiment. I had a couple that I had cleaned and aired out. These things are TUFF! I was very surprised. We really beat and threw these things around as we wanted to stress them and had backup water storage. In and out of the boats and cars and to the beach and back a number of times. Easy to refill. My only gripe was no hole to hang them from. May try to mod one with duct tape. May also try freezing them. Sorry about the lack of pictures. My camera didnt fare as well with the marine environment as the wine box bags. Give them a try. Good recycling tip!--KV
