In reply to BFG:
It's real. I have an order in and a receipt to prove it.
At my age, my fingers get numb from reaching into the fridge for a carton of milk, so if the gadget works it will be quite helpful for late Fall and early Spring climbing. Plus, the fact that the bag is insulated means one can supplement the warmth with chemical handwarmer packages, which I've used a lot in ordinary chalk bags and found to be only minimally effective.
I've tried bringing my gerbil but got tired of doing CPR after it chokes on chalk dust. Rumors are that there will be a gerbil defibrillator accessory for the lithium ion battery pack.
