I used it on 2 late season hunting trips. One was 14 days in -20 C northern canada. Other was -5 to -10 also northern canada.
It would freeze almost instantly in the line. I tried blowing the water back into the reservoir after sips and that helped.. but it still froze.. It did help if i filled the reservoir with warm water off the stove. But eventually it would still freeze in the line.
I would say this product is probably rated around 0'Celcius.. But any colder than that and you might as well just bring a water bottle. Which is what i had to do on both trips.
