Newbie question, but I continue to struggle with winter hydration. I have a Osprey backpack with a built in bladder with insulation around the hose. I was snow shoeing in 14 degree weather and the hose would freeze up.
What is the trick to winter hydration? A bottle held close to your body? If so, is it not a pain to unzip to get to the bottle? Thanks for all the help!!
