This time of year sees the temperature drop with the added problem of
frozen drinking water, especially in hydration bladders. Its always a
good idea to carry a water bottle that you can keep between clothing,
preventing the water from freezing.
A good piece of kit for this is the 1 litre Source Liquitainer. This
is a lightweight, foldable water bottle that even when full packs quite
flat. I attach a cord just under the screw cap and place this over my
head. The bottle is then worn between clothing, which prevents freezing.
When out for the night in freezing temperatures, place the full
Liquitainer in a dry bag, wrap a spare piece of clothing around both and
place within your sleeping bag.
CAUTION
Before setting out ensure that the Liquitainer is not damaged or leaks, this also goes for the dry bag.
ULTRA CAUTION
Do not add anti-freeze to your drinking water.
