Flexible nalgene wide mouth canteen - 96 ounce - Nalgene Canteen with Multi-Layer Film

Bought a pair of these to try out for a long trip. Filled them to the fill line and froze them into solid blocks. Worked great as ice blocks in the cooler, and as they melted it provided nice cold drinking water too.
