I, like probably most glider pilots, put my Camelbak behind my head
next to my battery. But a cautionary tale seems appropriate here.

Last Summer a club member had his glider totaled when his battery set
fire to his empty Camelbak. The probable causes, pinched wires and too
big a battery fuse, were certainly preventable. However, it's clear
that the Camelbak acted as tinder for the overheated battery, and the
fire may not have occurred if the Camelbak hadn't been placed next to
the battery.

Why dont you just put it behind your head like everyone
else?!

The seat pan / control column support wasnt designed
to have a camelbak 'lashed' to it and its easier to
work with gravity than against it!!
