      WELCOME TO THE CASCADECLIMBERS.COM FORUMS   02/03/18

      We have upgraded to new forum software as of late last year, and it makes everything here so much better!  It is now much easier to do pretty much anything, including write Trip Reports, sell gear, schedule climbing related events, and more. There is a new reputation system that allows for positive contributors to be recognized,  it is possible to tag content with identifiers, drag and drop in images, and it is much easier to embed multimedia content from Youtube, Vimeo, and more.  In all, the site is much more user friendly, bug free, and feature rich!   Whether you're a new user or a grizzled cascadeclimbers.com veteran, we think you'll love the new forums. Enjoy!

There isn't much I know of to keep the hose from freezing. That's the downside of the hydration packs.

Keep your water bottle in your sleeeping bag at night and in your jacket next to your body during the day if it's that cold.

 

Not a sure thing though... I've had a bottle freeze inside my down jacket while on the move.... when it's that cold it's time to stop and brew up on a regular timetable. bigdrink.gif

Camelbak make an insulated tube setup, which seems to help but the tube will still freeze. You can also fill your bladder with warm water (and use it as a hot water bottle overnight) at least that way it'll take longer to freeze.

in very cold temps that insulator won't work. instead, after each drink, clear the hose of water. ie. blow water out of the tube and back into the bladder.

There are a couple things you can do for your bladder.

 

1) If you decide to put your bladder in your pack, you may keep the bite valve in your collar. If you blow the water back into the bladder after every time you drink, less freezing will take place.

 

2) If you actually wear the camelbak backpack under your coat it will not freeze. Once again, keeping the tube under the jacket will help out immensely.

 

Good Luck,

If my bladder is in my pack, right against my back, it doesn't freeze. I keep the tube in there as well. I still have to take the pack off to drink, but don't have to "dig" for the bottle. I'm gonna try the blow the water back in thing.

All good advise.

 

But just drop one of those heat packets in next to the bottle before it starts to freeze.

Yeah, the insulation makes life better but if it gets cold enough the tube will always freeze. I've never had much luck blowing the water out of the tube, it always seems to work it's way back in and freeze up.

I use the blowback method and it works fine. As long as your bite valve doesn't leak, the fluid shouldn't creep back down the tube. The only problem is that if you forget one time, the tube freezes and its all over.

Made an insulator for the tube out of pipe insulation I bought at home depot for about $3.50. Took about five minutes to cut the foam so that the interior channel was the appropriate size and tape up. Works great.
