Ok thanksIf you are plannign to be below freezing then you need to keep most filters warm. I keep my HyroBlue Versa in a small plastic bag inside my shirt against my body during the day (not in a pocket) and it wroks very well to keep it from freezing and getting damaged. I have just started using a passport pouch inside my shirt so I don't accidentally loose my filter if I untuck my shirt to cool off on a harder hike. At night I keep in inside my sleeping bag to avoid freezing.
I always bring tablets as chemical treatment of your water may be affected (time) by colder temperature it will not be "broken" like a filter but chemical treatment does not clean your water so a pre-filter is oftern desired. Many use coffee filters or microfiber diesel filters.
