Beach Vacation Accessory Turtleback Sand Coaster Drink Holder, Pack of 4

These are awesome. Just what I wanted for camping - not wanting to repeat that time I woke up in a puddle inside the tent because a liter of water spilled.They're a bit of a weird shape for packing gear as I do - in a Tetris like way. But they're worth it, and MADE IN THE USA! And they fit a wider bottle like a nalgene.Happy to have these and might even buy some more as gifts.Simple product but a great camping hack.
