Title: water bladder
Post by power_bent on Jun 17^th, 2011, 9:12am

I wrap my 70 oz water baldder with a windshield cover and it made a world of difference. It lasted twice a long staying cold and i was able to drink it all to the end and it was still cold. I put ice in bladder and filled rest with water and it was 5 am and at 1 pm at the last drop of water is was pretty cool to drink.I also have this bladder wrap in my dual centry fastback bag on my trike.

Thanks Caroline, I will be looking into the unbottle you told me about too.

I use the thin foam sheet from the packaging from something electronic I bought some time ago. I have a hard time throwing stuff like that away. :-/

The Camelbak Unbottle really does work well. It has such good insulation that I have to be careful about putting too much ice in it, or I'll run out of water with ice still in it. Mine has taken over six years of abuse (Greg and I even ran over it one day).

I used to have a sheet of aluminized bubble wrap, well it looked like bubble wrap but was made from a heavier material, and like I said it was aluminized on one side to reflect heat. Original use was to build emergency animal shelters for farm animals caught out in the open, also for people. In 0F temperatures one human could keep the inside of a simple tube tent above 40F, cattle shelters had to have open doors to keep from overheating the animals. good stuff, I also used to have a drink cooler made from it. I haven't seen any since the early 1990s but if you could find some it would make for a good bladder carrier.

EDIT: I should have used Google before I posted that. Here is a supplier for the stuff: http://www.radiantguard.com/bubble-insulation.html

If you want to keep the drinks cold, do you put the aluminum side facing in or out?

That was quite the tuff unbottle Bud had. I thought I'd run over a critter!

The aluminized surface is a radiant barrier, so it should be facing out.

I got a roll of something similar at Lowe's--enough to do a few hundred bottles. I was using it for under house insulation.

I thought you didn't drink water.....and I checked Mark L's blog and he didn't ride Saturday..... what is this world coming to? Am I in some sort of twilight zone? ;D ;D[/quote]

I drink water, just don't carry any with me, usually (Extra weight, you know). :) Don't like it, but have to make an exception during real hot weather, when rest stops are far between.

Amateurs. Real men put beer in their camelbaks.

Wouldn't work for me. I have a hard enough time maintaining a line just drinking water. :)

Bob, thanks for bringing me the aluminized insulation. I made a bag out of it to hold my CamelBak bladder. Put it and the bladder in one of my Musashi's side bags, before I rode today's Cow Creek Country Classic ride. I took the bladder out of my refrigerator this morning about 5:45 AM and put it in the insulating bag. At 1:00 PM the water left in the bladder was still a little cool. Would have been even cooler, if I had put some ice in the bladder.

Glad to hear it. My setup melted the ice by the half way point on our metric, but the water was still cool after 2 1/2 hours on the road. Added more ice at the half way stop. It did better than the Polar bottle.

It's counter-intuitive but as a drink cooler the aluminum side faces in. There has to be an air space between the aluminum and the heat source, so the aluminum faces the cold side when the insulation is in contact with the container. To keep the drink warm the aluminum side would face out.[/quote]

Reflective surfaces do provide added resisistance to heat transfer when facing an air space that is a part of a composite construction. An example is the "Polar Bottle" which has a 3 mm airspace encapsulating a thin aluminized plastic sheeting with a highly reflective surface facing in. With my bladder insulation there is no air space, because the insulation is in direct contact with the bladder. In addition to heat transfer from the outside, radiation also causes heat gain. In the case of my insulating bag the reflective surface should face the source of radiation, which is from the outside. The insulation I'm using actually has reflective surfaces on both sides. I put the reflective surface in the best condition on the outside.
