It does not provide the greatest "bang-around" protection, but I've had no problems. Closest thing I found on the web is this, $20. [Search for "surplus medical bag"]. I suspect it has a shoulder strap. I wish I could see inside it to know if there are any internal compartments. The pouches on the outside would not seem to give much protection. I've found back packs to be inconvenient. I've been thinking about one of those tough Pelican cases with the foam cutouts for travel.
