The CNOC 42 mm 3 litre water container is a bit heavier than the equivalent Katadyn 42mm 3 litre water container that I normally use with the BeFree filter. However, the CNOC is much easier to fill when you are hanging over the edge of a river bank scooping up water due to its wide mouth which is similar to that of many backpack water bladder openings. It’s also easier to clean due to openings at either end compared to the single opening on the Katadyn. Overall, I’m pleased with its functionality and I’d recommend it to anyone who uses a BeFree filter.
Unbreakable frames that feel comfortable to wear. Clear lens with no reflection.
The fit is great, as I have larger legs so the extra size is good. They are well made and they should last a long time.
