As I mentioned in the Peterson Lake Cabin post, I love my new water bag. It's smaller than a deck of cards, weighs in at less than 3 oz, yet scoops up 10 liters (2.6 gallons) of water in one swoop.
The bag stands up on its own, so you fill it and forget it until you need more water. Just store it away from children or animals as the bag is fabric it can be pushed or tugged over with a splash.
It is made from waterproofed nylon fabric. It has a thick cloth handle and a small handle on the side of the bag to assist with pouring.
We used the bag to collect enough water for two people for 24 hours for cooking, drinking and cleaning. In the end we poured out more than half of it because it was unneeded.
On the Chilkoot we saw several hikers with similar bags that they filled with freezing glacial runoff and then set aside to warm in the sun.
It is a luxury item, but one that both Mr. X and I agree is worth it weight, especially when camping in wet, cold SE Alaska.
