Wide-Mouth Cantene

I have the 96 oz. This thing is perfect for use with larger groups, areas where you have to haul water a distance, or need to filter a lot of water. It collapses very small and weighs nothing. This also comes in a narrow mouth. I recommend the wide mouth because it fill and pours much easier.

Having been a user of the 32 oz size as well as the 48 oz one, I have found these Nalgene units to be very durable and perfect for my needs. I use a Pur Pioneer filter (no longer made) that I can attach directly to the threaded top and it makes purifying water an easier task. I find the 48 oz size to be the one I take the majority of the time and the one I've used now is three years old.

I've used the 32 and 48 oz. versions for a while now, normally in combination with an ExStream filter. They're cheap, lightweight, and fold down very compactly when empty.

The warning about keeping them away from sharp objects should be heeded, though, as the containers obviously aren't as robust as molded plastic. One of my 48 oz. containers developed a small puncture after only a couple of uses, rendering it useless; I'm guessing it came off the worse for wear with an encounter with my crampons.

Edit: I originally rated this 5/5. Another of these containers developed a leak, this time for no discernible reason. I'm adjusting my vote down to 2 stars because I find now that I just don't trust these things to hold liquid when I need it.

These things are great in certain circumstances. I use the 96 oz version while at camp. It allows me to go to the river fewer times to filter water and does not take up room or add weight when not in use.



The down side is that it isn't very stable at sitting up without the lid on.

This system seems a little more sturdy than the platypust hoser things. The wide mouth is a plus. The only down side is that the attatchment for the tube on the lid does not rotate so the hose can feed off to one side or the other. This can lead to pinching in the pack if not addressed. They are much more comfortable to sleep with.

I'm considering using one of the 48oz ones for my pee bottle on Denali. It says that they are good down to -20F°, but just wondered if anyone has had any experience with these in COLD weather yet. I will be testing this asap, so I can update this post once I have tried it out. Thanks in advance for any input.
