(As an aside, McNett tells me that their product development "skunk works" has taken my hack to heart and is developing a new product like it.)
Anyway, when I hurried to put together a trek up to the John Muir Wilderness area west of Bishop, CA, I forgot something very important.
|Campsite next to Hungry Packer Lake, little over 11,000 ft in John Muir Wilderness|
As expected, it dropped to about 20 degrees -- balmy compared to the way-below-zero temps on my winter mountaineering treks ... but still cold enough to sleep with the Camelbak insde my sleeping bag to keep it (and my clean water) from freezing.
Only problem is that I had left my low-land, running valve on the drink tube (below):
Fortunately, my below-zero-rated bag is synthetic fill and my long-johns wick away moisture. I still needed water, so stuck the valve in a Zip-Loc and went back to sleep.
I stuck my usual valve (below) on as soon as I got home.
