Lol, sounds right.

I know of no one that uses bladders in sustained, real cold. Too problematic. Not sure about Kilimanjaro, never been. Doesn’t sound very severe so they might be fine. I’ll defer to your “hose clearing” experience in this case. I just know in sustained single digits and lower they’re useless, and that’s not a guess. smile
