Lost: Gray Camelback Snoblast (used for snowboarding). See picture here: http://www.rei.com/product/759181/camelbak-snoblast-hydration-ski-pack-70-oz. It has a neoprene covered tube, and some neoprene insulation inside, so the water doesn't freeze while skiing. (I think it's gray, I am colorblind.)
I was dancing at the Pyramid at 10:00 and Esplanade for about 5 minutes, when I returned to my bag it was gone.
It might have had a Petzl headlamp in it, or a blue scarf, but I'm not sure exactly what was in the bag. Nothing super valuable.
I would love to have it back, though, since new camelbacks are pricey, pricey.
