Do you feel like you’re running out of time with Christmas only four days away? Need a last minute idea to stuff your scout’s stocking? How about a Nalgene water bottle? These are great bottles; inexpensive and durable with several options to choose from. The kind I’m recommending (shown below) comes in two sizes, 16 or 32 ounce with either a wide mouth or a narrow one. You can pick from a variety of different colors, all compatible with the typical water filter and purification system. The loop on the lid can also clip to a carabiner hooked to your backpack for convenient access while hiking. Priced at under $10, this is an awesome gift for as long-lasting as this bottle has been for me (I have one going on 10 years old)! 
The 32 oz. wide mouth version is a popular choice to use as the container for home-made Emergency and Survival Kits.
Nalgene also offers a 32 oz. canteen bottle if you like that style better.
