How do I thermalize my Dakine Reservoir?

post #1 of 20
Thread Starter 
I have the Dakine Helipro backpack and I've had the 100 OZ. reservoir for awhile. However, when it's below 20 degress F the bite valve and the line freezes up. Dakine does not sell a thermal kit for its reservoirs. Can I use the Camelbak one or do I have to buy the Camelbak reservoir as well? Anybody have this issue with the Dakine reservoirs? Thanks.

The Camelbak Snowblast and a few other Camelbaks have an insulated tube and it then zips into the shoulder harness.
Inside the harness near the spout is a pocket for a handwarmer.
Haven't tried it in really cold temps yet.
Should be able to rig something up if yours doesn't have it.

The thermal Camelbak doesnt work, it too freezes up. Others here have had some success with blowing air into the tube when your done drinking to clear out any water that would get frozen.

Other than buying a heated hydration unit, or rigging up your own, the next best thing is to simply keep the tube or the whole system under your jacket.

Just to bring up this old thread. I too bought a Camelbak snowblast to use this winter while skiing/snowshoeing etc. I've had it out 3 or 4 times now with all this great snow we've had up here in Quebec. No luck! It freezes both when worn externally and internally - under my jacket. Blowing out the liquid back into the bladder works but only temporarily. Has anyone had luck with those bite valve covers? Usually made of neoprene i believe. I bought the pack to hydrate, not just to carry my extra gloves , food, etc....

Suggestions?

I have the cover does nothing.

Crazy thought here - If you added electrolyte powder (powerade or gatorade) to plain water would the salt in it lower the freezing point making it less likely to freeze? Would it make any significant difference or just gunk up the camelback?

Put warm water in, blow back after each swig - works for me. BUT haven't used it below -15c or so.

My winterized CamelBak was icing up on me a couple weeks ago when temps were in the 15F range over the day. Really ticked me off -- I basically carried around 10 lbs of water on my back for no reason, until I went in at lunchtime and thawed it out. I always blow back into the reservoir after I drink, but it didn't matter this time.

Exactly how I felt, pisses me off.

If I dont get a heated unit this season I might try the hand warmer trick to see if it makes a difference.

I find a mix of 50% blue Power-Ade and 50% Absolut vodka never freezes on me.

Negative. On using gator-ade and other related products. That's what i've had in the pack. Still freezes.

I'll try using the little hot packs nex time and report. Just noticed that as posted earlier...there is a tiny mesh pocketin the strap/enclosure. Sweet. let's see if it works. This is in temps of -15C and below.

Put a handwarmer in the main pack too and blow back will work better.

I fully intend to scavenge a Hottronics for this duty.

I used the Camelbak neoprene sleeve and bite valve cover with the blow back method, works until single digits with wind chill. That sucked.
You can always go old school:

1) use a pack with the drink hose routed through the strap, like some Dakine packs
2) also use Camelbak's insulated cover over the drink hose, if yours didn't come with it
3) blow back the water into the bladder after drinking
4) drink on every lift ride -- keeps the water moving

5) -- last resort -- fill bladder with warm water

I need to try that hand warmer suggestion next time -- it could do the trick.

Besides blowing the liquid back into the pack, also squeeze the bite valve to get the last few drops of moisture out of the valve (sorta like - you know what..).

The small amount of moisture in the bite valve is what will freeze up just enough to stop you getting a drink even after you've blown it back in.

Btw, you can still fit a Camelbak insulting cover over a Dakine hose within the Dakine shoulder strap (works on my Quad at least), and Camelbak covers don't fit Dakine bite valves.

I do this as well but have never skied at temps colder than 8F and as long as I remember to blow back no issues with freezing. I wear mine outside the jacket shell and sometimes stick an extra neck gator in the pack.

Well I no longer have to worry about this, scored a heated hydration pack for Christmas. My Camelbak has been demoted to just warm weather use now.
