Wearing the D Gear

What seems like many years ago I read about Bill King running marathons with a glucose meter strapped on his wrist. I tried a few ways to do that myself, but it seemed like more hassle than it was worth. It's really not easy to insert a strip, get a drop of blood, and touch it to the strip, all pretty much using one hand. It's more convenient to carry the meter elsewhere, like a SPIbelt, and take it out when you need it.
But at Ironman Arizona in 2009, I saw Bill Carlson with a Dexcom receiver in a plastic bag duct-taped to his forearm. That looked convenient, but painful to remove. Bill had his current blood sugar trend at the touch of a button, right there like a wrist watch.
So I've given some thought, and done some experiments, in that direction.
My first thoughts went toward sleeve-like things, cheap garments from a thrift store, cut-off tube socks or sleeves with some modification to hold the Dexcom.
I had this idea that all I really needed to do was to wrap the Dexcom in plastic wrap. Then I thought, well, just wrap it all the way around my arm. It's actually difficult to wrap my arm and the Dexcom together that way, though, and it would become a sweaty mess very quickly.
I had used stretch bandage that comes in rolls, one brand is called Co-Band, to attach some things to my bike before. It's the stuff they wrap your elbow in when you give blood. It seemed like this might work for this purpose also.
So here's something that seemed to work, the Dexcom receiver wrapped in plastic wrap with lots of plastic hanging off the ends, then the ends wrapped onto my arm using stretch bandage material.

This seems to hang on well enough while biking. I haven't tried it on a run yet. I'll probably go back to the sleeve idea, since it would save a lot of time in the swim to bike transition to have something I could just pull on, instead of wrapping my arm. I can't see fitting my wetsuit over this, even if I wanted to.
