I've got a pretty nice Stethoscope that I carry with me since I use it for work, but I'm struggling with how to transport it in my backpack. Right now it's just sitting loose in the main compartment of my North Face Surge backpack. Has anyone come up with some innovate storage techniques for carrying one of these around in your bag? I just can't seem to find a perfect pocket inside the bag, or an attachment point on the outside of the bag, so I'm looking for ideas. Thank you.
