Forest Ranger Canteen

This is a good cheap water bottle. I like the rectangular shape better than a Nalgene because it fits better in the back pocket of a vest. The drawback is that the cap will break fairly easily if the bottle drops while full of water. Not ideal in remote situations, but easy enough to prevent.

I use these canteens for work; we get them through the GSA system on wildfires. They fit nicely in outside pockets on many packs and fit nicely in my hand, making it easy to stay hydrated. They freeze and thaw well. I've left a full bottle in the truck overnight during winter, and it didn't split or crack, just bulged a bit and returned to its normal shape when it thawed. I always mark mine with a strip of blue electrical tape near the top to indicate it's a water bottle, and to add some grip. They're inexpensive, so I keep one on my desk at the office, on my desk in my home office, in my vehicles, and in the saddle bag on my motorcycle. There's no excuse to not have a water bottle if you order a half-dozen of these. The only drawback is the cap breaks easily if you drop the bottle, but you can replace it with any 33/400 plastic cap (if it was on something safe to consume), or order some from a packaging supplier online.

I have been using these type of canteens for over 17 years. They work well. I have never had issues with them leaking. They have a long life. I have frozen mine in the freezer, caused the plastic to bulge and they still never broke.
