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.

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.

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!

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.

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.
