Q:
Do water bladders sweat inside a daypack?
Do water bladders sweat inside a daypack? My daypack is big enough to hold a bladder, but I'm worried my other stuff will get soggy if I pack next to a bladder. I worrying for nothing? No Name Given
What you're thinking about, of course, is not the same thingcondensation is what you have in mind. And in theory it's quite possible. If you have a bladder full of cold water, warm, moist air from around you will inevitably cause some condensation, or "sweating." Enough to be a problem? Not likely. Besides, most bladder makers sell an insulated bag that the bladder fits into. Cascade Designs makes a product called a Hydration Insulator, which does exactly that: $18, and no sweat
