After 4 hours of hiking, the bladders seem to have as much water left on them as I would expect - so, there's not a severe leak. But the bottom of the pack - underneath that sleeve is wet.
Could this be condensation? For a while, I has been keeping the bladder in the fridge overnight, so I'd have the cold water while hiking. At that point, I was pretty sure that condensation was the answer. But now I keep the bladder in the trunk of the car overnight, and still have the same problem. What's Goin On???
Thanks!
