A Reliable Standard
on January 20, 2015
I like it, but think the Nalgene alternative is better. This is reliable and it should stand up to a fair amount of abuse, but for just about the same amount of money, I think the BPA free Nalgene model is a better buy. It is slightly lighter, and it still nests inside a standard GI carrier and inside the GI stainless steel cup, but this is opaque while the Nalgene is semi-transparent. A good thing for when you are outdoors and you want to see what sort of bugs and debris may be floating in your water.
I also like being able to see the clarity of the water in the container both before and after filtering.
This one may be sturdier than the Nalgene, which is probably why our troops use this instead of the Nalgene, but I don't know that I am going to use it so hard that I will need that extra bulk and weight. I have them both, so I will compare as I use them and update if necessary.
